yetchh Posted October 28, 2019 Author Share Posted October 28, 2019 Almost got there today amongst family duties, in a bit of a rush as I go to melbs for 12 days on Wed, drive me nuts if I don't get it going before then.. She's all together, got a small coolant leak from the water temp sensor which I have to sort.. Pump is in, can't prime it tho as I ran out of hose clamps.. 2 Quote Link to comment Share on other sites More sharing options...
yetchh Posted October 29, 2019 Author Share Posted October 29, 2019 Well it runs.. But I have to throw gas down the tb. It almost ran by itself... kind of. Master fuel is set to 128 from factory but the only time it even looked like running was when I wound it right out to 255 (max) and it sort of sputtered along then died when I touched the throttle.. It says the injectors are running, and the fuel pump is going but no runny run.. I'm out of time tho, "have" to go on holiday and enjoy myself.. Gonna have to check fuel pressure when I get back, injectors haven't been used for 18 years so I'm wondering if they're stuck.. anyone in chch have experience with link g1's 3 Quote Link to comment Share on other sites More sharing options...
yetchh Posted November 14, 2019 Author Share Posted November 14, 2019 Hmhmmm.. Was a blown fuse to the pump..... she's alive Got no o2 sensor at the moment so I'll let it run on the base map for now and just adjust a couple of things 8 1 Quote Link to comment Share on other sites More sharing options...
yetchh Posted November 15, 2019 Author Share Posted November 15, 2019 Got a small issue.. Over 1500rpm she's pretty smooth and the pump is quiet but when I drop too idle about 700rpm the pump gets noisy and does a slow pulse.. like its sucking air then fuel, the idle also gets rough then smooth corresponding with the pump.. Any ideas? For some reason my temp sensor is also giving me strange readings.. 34 and falling or 96 and rising.. Quote Link to comment Share on other sites More sharing options...
cletus Posted November 16, 2019 Share Posted November 16, 2019 Return too small/blocked/ regulator not regulating correctly and making the pump work hard ? Have you got a pressure gauge on it? 3 Quote Link to comment Share on other sites More sharing options...
yetchh Posted November 17, 2019 Author Share Posted November 17, 2019 Thinking about it I reckon it's vapour lock at the feed end of the pump.. When the engine stops using fuel at idle and running fuel through the pump (which gets quite hot) I think it vaporises then pump overcomes it and sucks some more etc etc.. 1 Quote Link to comment Share on other sites More sharing options...
yetchh Posted November 20, 2019 Author Share Posted November 20, 2019 Think I could've found the problem... Ordered a turbosmart fpr800.. See how it goes. Still have to figure out the strange water temp readings and I also think I'm pulling to much amperage through the main relay as it sticks on when I run the car, have to pull the main feed off to turn it off.. 3 Quote Link to comment Share on other sites More sharing options...
yetchh Posted December 1, 2019 Author Share Posted December 1, 2019 Finally had a bit of time to work on this.. Fpr arrived in the mail, So bought some fittings to plumb it up, shit picture.. 5 Quote Link to comment Share on other sites More sharing options...
Popular Post yetchh Posted December 1, 2019 Author Popular Post Share Posted December 1, 2019 Also got the proper NTC sender.. The one I had was a PTC sender which was only used in the very early G1's which explains the problem.. This was set up for the first time in about 1997 on the cheapest link at the time which I assume was an lemv1. They switched to NTC after that.. Anyway, temp reads properly now. Got a new 40 amp relay but even that sticks on after I switch the ignition off although tapping this one solves the problem. Did try to get a 50 amp but repco/supercrap = shit selection. Might just go all out and get a 100 amp. Plumbed up the fpr last night, she's pretty tight in there so might have to reassess the plumbing as the outlet sits directly over the tank return line, which means a straight hose that puts pressure on the fittings /fpr mount when the engine rocks.. Doesn't hold pressure for very long so somethings amiss there.. Set it to run about 38psi, got no idea what they run at factory as I can't find any info at all on the egi MA.. Cunt Also managed to take her for her maiden drive today, Went really well.. Then didn't. Developed another fuel related issue with the pump somehow sucking air out of the tank, also now that the pumps cycling more fuel it's pulling more shit out of the tank. Went hard for about 100m then started missing/surging and eventually dying.. Typical. After sitting there trying to get the pump to prime I realised the vacuum line for the brakes was off and sucking a fair amount of air. Made fuck all difference once I reconnected it although I was able to limp home. Have one of those glass fuel bowls plumbed up just after the tank so I can see what's going on.. Looks like a fucking sodastream. All teething problems I guess but at least the pumps now not overheating.. 12 Quote Link to comment Share on other sites More sharing options...
yetchh Posted December 8, 2019 Author Share Posted December 8, 2019 Had a total guts full of that gas tank, so pulled it out.. Prick.. Pulled out the sender which had a bit of white oxide on it, As did the tank, but more importantly.. Varnish.. 4 Quote Link to comment Share on other sites More sharing options...
Popular Post yetchh Posted December 8, 2019 Author Popular Post Share Posted December 8, 2019 This shit has been the bane of my life for the last 5 years, clogging everything up. Read today online that the best way to get rid of varnish is with caustic soda, so off to miter 10 I went and bought 500g of sodium hydroxide. Put it in with 7 ish liters of water.. Neck minute.. Beer anyone? That was extremely satisfying. Why the fuck I didn't do this all those years ago I'll never know but the results speak for themselves. 12 2 Quote Link to comment Share on other sites More sharing options...
yetchh Posted December 8, 2019 Author Share Posted December 8, 2019 Nice and clean.. Gave it a rinse out with detergent and plenty of water, the half a litre of meths to get all the water out, let it sit in the sun for everything to evaporate while I had a beer.. Still a bit of the white oxide around but I'm not so worried about that, hopefully now I can have some trouble free motoring instead of stopping (sometimes every 5 km) to try and get rid of a blockage.. 9 Quote Link to comment Share on other sites More sharing options...
Popular Post yetchh Posted December 8, 2019 Author Popular Post Share Posted December 8, 2019 In other news, got a couple of other fittings to plumb up the fpr, Shows the proximity of the return line in relation to the fpr mount.. Worlds shortest bit of hose, And all together, also put a 45 degree barb on the outlet to bend the hose so when the engine rocks is not jamming straight up into the fpr.. Started her up after I put the tank back in tonight and its definitely seems better, not surging like it was before. Readjusted the pressure to 40psi at idle, so hopefully I can take her for a drive.. Really need to get an O2 sorted, maybe I need to get my hands on an innovate.. 10 Quote Link to comment Share on other sites More sharing options...
yetchh Posted December 15, 2019 Author Share Posted December 15, 2019 Some encouraging news, after my last outing I was too paranoid to drive it to the Christmas meet. Took it out this arvo for a spin round the block and it seems to be going good. Did have a massive flat spot of idle but I fiddled with some of the settings regarding low rev accel and injector wake and it looks to mostly have disappeared. Fuck does it go better than the carb, doesn't run out of puff at 4k like it did and actually pulled way harder than I was expecting, had to back off the gas as it just kept going.. Good Times. Just have to tidy up the plumbing for the fuel pump at the back and get myself an air filter (and a wideband) I also need to sort a fan but I think I'm just gonna get a viscous hub of an fe that way it'll flow more air and I won't have to worry about wiring up a fan and overloading my alternator, then she should be good to go.. Speaking of wide band, not really sure which one to get. Was looking at this one But I guess I should let the link do all the boat cut etc since all the functions are the and just use it solely for tuning in which case I should just get this one, Or go analogue and get this.. Maybe a little Xmas present to myself, then I can tune other things.. 8 Quote Link to comment Share on other sites More sharing options...

Popular Post yetchh Posted December 22, 2019 Author Popular Post Share Posted December 22, 2019 Got a little bit more adventurous yesterday and went for a longer drive out on the 80k zone so I could open her up a bit. Goes so much better, who would've thunk that efi and an 60mm Tb would make this sort of change. Finally found some info on this particular iteration of the f/ma, came out 82 the 1982 luce 2000 sg-s and not the cosmo like I previously thought, no wonder I couldn't find anything.. Was pretty healthy too really, considering they "upgraded" to the fe, 120hp/167nm vs the 12v fe 120/178. I was always of the opinion that it was a total boat anchor at only 90hp, I've done bit of work to them in the past and they've gone pretty good but efi is hands down the best modification, shits all over the 45dcoe I had on my 626.. Just don't remember it being this quick sans turbo.. Anyway like I said took for a spin, got it up to about 5500rpm a few times.. Once it hits about 4k you can really feel the vibration through the pedal compared to the carb, think it comes down to the way the linkage is orientated so at wot the cable is sitting at almost right angles to the linkage (kinda hard to explain without a pic) might need to adjust it round a bit. All went good till (luckily) I got home and it started running like a bag of dicks again, but this time an electrical miss, down a cylinder. Checked leads and they were definitely firing, pulled off an injector plug.. ahhh. 4 and 2 not pulsing so inj pinout #1 and sure enough when I wobbled the cable it came back. Ended up being some dry solder joints on the main plug, resoldered them and bob's. Also managed to get a viscous hub of an fe, was pretty loose so I topped it up with some silicon oil. They work a bit different from the Asian hubs on the toyotas as they unbolt and come apart in half whereas these don't come apart at all, instead the of a bimetallic coil they have a strip that when hot bows out releasing a little plunger type pin underneath which in turn somehow activates a valve inside. To top it up you have to get the oil through that little hole whilst letting air out (it was a cunt) works anyway and is much quieter than the fixed fan that was previously on there. Got a new oil pressure sender as well, the old one was leaking like a mofo.. No wonder the bottom half of the engine is covered in shit.. Ended up getting an aem wideband. Reviews said it was the best but more expensive than the innovate, trademe disagreed and someone had them for about 60 bucks less. I'll weld the bung on in the new year and get about tuning it a bit. Here's a great pic to prove I actually did something and didn't just want to talk shit, I forgot to take pics of everything else.. 18 Quote Link to comment Share on other sites More sharing options...
Popular Post yetchh Posted February 16, 2020 Author Popular Post Share Posted February 16, 2020 Fuck, totally just overheated it.. Was taking it out for a smash after just getting rid of a big flat spot off idle, was just cruising after the fact when I smelt a bit of hot oil. Having just done a skid (and giving it an oil and filter yesterday) didn't think to much of it. Gave it the boot out of a round about and it stumbled a bit.. bit odd. Got home it was really smelling and the tappets were noisy, smoking from the breather and the hoses were soft. Fucken blew a small bypass hose off the water pump, it was only held on with a wire clip and I never thought much of it since its been there for god knows how long.. Anyway put a new clamp on it and slowly dribbled water in while it was idling and the temps came back, noises also stopped.. Hope I haven't warped the head. Its o-ringed for boost so it shouldn't blow gasses, just oil and water.... Typical. Haven't had a lot of time to work on this, but have done a couple of minors.. Like extending the accel cable so it's in a nice wide curve. Don't get the vibration much now except for it'll randomly kind of buzz around 4-5k I think it's where it comes through the firewall and connects to the pedal somehow. Plumbed the fuel pump better, previously was just lots of hoses.. Then it wouldn't run... Ahhh, what now? Whoops.. Forgot about that bit. Bought a k&n filter so I don't suck some small dog in while I'm ironing out the bugs, By the way you can see the offending hose just under the thermostat housing above. Fixed the broken stud on the bonnet, not sure if I trust its strength.. I then trimmed and tapped the thread back on it.. Gonna take it in for a wof this week and if it passes I'll then stick the wideband on it and getting it running at its best. Reason being is I don't want to weld the bung on this exhaust only for it to be failed.. Might just get a no weld bung as eventually I'll bin this exhaust. Was gonna turbo it for nats but I decided without cert insurance is void so I'll do it when I get back.. Good times.. 10 Quote Link to comment Share on other sites More sharing options...

yetchh Posted February 27, 2020 Author Share Posted February 27, 2020 Ok is not that fast just faster than it was, and spin wheels friendly. Did a gps accel test, 0-100 in 12 sec.. Does rev out a whole lot more tho, excited to go for a big drive. 6 Quote Link to comment Share on other sites More sharing options...
Popular Post yetchh Posted February 28, 2020 Author Popular Post Share Posted February 28, 2020 Went for blat to the hilltop and back (about 140km) , all was well.. Edit*. Think the tyres I have from 1995 are past their use by date.. I drove it pretty hard I think they were definitely on the edge. Had the back of the car let go on many occasions.. Lots of squealing 25 Quote Link to comment Share on other sites More sharing options...
