Another go at the fueling realised had base pressure wrong when I calculated it.... Re ran the calculation made very little difference to ms/g like 01ms so fudged it bumped it down 5ms.

While i was In there I toggled off the EGR and set it run off a single narrowband sensor which I think I'll re fit next to the wideband as it's only 12 months old and car runs nice on these. 

Started up no longer stinks of fuel and started much easier. Now to let the car get up to temp and let the trims sort the rest out think im in ball park now.

Also figured out a definition file glitch which was stopping me reading  data on Tunerpro could flash in fine but information coming in was wildly inaccurate 28000rpm 1200c on inlet air temp.

Pft

Kind of win/lose situation fitting the crossover pipe low in engine bay it allows heat to piss off under car, but it's complicated the intercooler pipes. Have heard horror overheating stories from most that run them higher so happy with the compromise.

Made up a stainless lower radiator pipe today with intention to put some fittings In to water cool the turbo. Its quite close to the crossover pipe so should help it survive down there.

As for the intercooler pipes I think if I squeeze pipe oval may squeeze under headlights. Could be wrong will see.

Did some more stuff on this today got it to a point it it runs and drives ok few gremlins to chase is still horrendously rich and idles like a sprint car. I've got a 1500rpm idle so could be an IAC valve fault (likely) It shot its plunger across garage, or a vacuum leak.

Intercooler pipework no easy route unless I cut holes in Bodywork then it's piss easy but battery has to go elsewhere.

Exhaust into rest of system 2-3 bends and a v band shouldn't be too hard 89mm V bands are ridiculously huge how to not warp that.....

Some more wiring and a bit of a road tuning session should be a happening thing.

Jeeze it sounds like a fighter jet though very happy turbo takes about 30sec to wind down when you turn it off.

There's no videos of that GWM engine running at least so your still 6 up on them. Just an Asian exec making finger guns at a car show.

If you could make a parody that would be excellent and end it with a running engine in an imp.

Yeah seems to be reinventing the wheel abit. I would emulate something like you see in most EFI drag cars, heaps of data logging, driveshaft speed, accel meters etc, then usual stuff like wideband and tune it for the track/day/change in parts.

Agree on reinventing wheel a bit....I may go with 2 strain gauges one either engine mount and plug it in to the spare channel on my ECU see if it gives any promising data or just noise. Fairly cheap to do if it's garbage I'll spend money elsewhere. 

Sounds like a Cummins

Shouldnt factory base map off load/boost be ok? surely turbo/intercooler/piping shouldnt change things too much ?

Yeah the airflow meter is at throttle body so no dramas there. Turbos just hanging out blowing leaves off driveway at moment.

Couldn't wait changed an old map I used at drag day then tweaked the injector flowrate using an online calculator. Measured in Ms/gram very confusing for me....

Flashed a good Bin file in then flashed the Calibration on top and bugger me it fired straight up! Let it run for 30 seconds that'll do it's really loud! Don't want to piss neighbours off after dark local pukekos were losing their shit.

And im unsure if my turbo was getting oil so will confirm tmrw then do a video after checking if anything is resting on exhaust.

Fuck yeah!!

Did last of wiring to get running tonight 

Kicked it in guts crank no start kept cranking got fault code no crank signal did the Nintendo terminal check undid ignition module blew on it tried again, sputtered and coughed out intake fuck firing order out fixed that.

Cranks mint splutters runs for 4 seconds dies massive clouds of black smoke.

So she's way to rich I was hoping for a start before reflashing to take one variable out in case it won't start.

So let's build a base map in bed Iater tonight was given one that has correct specs but turns out isn't compatible with my ecu.

will copy over the injector info into my current map flash in and try again on weekend.

with that investment is it not that far off just going to a dyno for a day.  seems stupid to  put 500 and a whooooole bunch of your time into making it all work to somethign thats half assed anyways. when a day on dyno be 1k or whatever and your done.

I hear you for sure it may go to a dyno initially to get the driveablity sorted but I want to develop further afterwards. If im able to set up some of the dyno features in the car I can use those as engine protection later on.

In theory could be a cheap way for others if it works strain gauges are cheap and give good information once you can read it through software im just wanting a non commercial solution to it so it's affordable.

Yeah it realistically could probably the subframe under the mount

Could the strain gauge go in the engine mount? Would that lessen the wonky readings from bumps etc?

Could be a good location thinner metal more deflection so may yield a wider range of readings. I like your thinking there.

For background i used to Install these on machines like lifting davits and forklifts to give live data to the operator on the loading.

I've now twigged it could be useful for tuning and wonder what automotive monitoring equipment might be suitable. 

Hmm If I was going to try it would need a fairly consistent smooth road to give it beans on. Like perhaps an airfield or drag strip I think i can handle that.

Find a way of filtering the data a bit harder, I think I may get in touch with Mantracourt and see what they recommend a Bluetooth module is about $500 from them and gets access to some very powerful and software.

Hardest part would be calibration though accuracy isn't overly important I just want to be able to see a graph where I can figure out if I made more torque than last run after tuning tweaks.

I used to be the distributor for Delphi Mantracourt so can get their gear but it expensive formula 1 use it..... I'm wondering if a oscilloscope app could be used to just record the voltage and compare against the data from ecu. 

Plan would Involve 2 of these one on each side to give a total torque figure. 

Hi All I've had an idea to add some strain gauges into my rear suspension to give torque readings while road tuning so I can go one better than just the yup that feels faster scenario I would be using otherwise.

Ideally I'd feed it into the ecu but I think I may be running out of capacity on mine.

What else could be used (cheaply) to monitor a mv/v signal that could maybe give a dashboard readout on a screen with live or peak data readout? 

Decided these alloy powder coated intercooler pipes that came with kit are mostly useless big radius bends and some have been butchered and are paper thin so won't fit in 99% percent of gaps im going to need to squeeze through, Bugger it stainless it is have ordered bends of Aliexpress found to be pretty good quality so far. V band for downpipe and some 3" straight for intercooler bought locally. 

Spool noises this coming week hopefully. So I can drive it on ramps and build intercooler pipes.

Wrapped up 90% of wiring today surprisingly there was loops bundled up in factory loom to allow  most things to reach new locations. Only thing left to do is solder in the sub loom I made up to send the TPS and idle control wiring around back of engine. Have done my best to have no wiring near hotside of turbo you can see a small loom heading to radiator that feeds some air-conditioning and body stuff.

Spark plug leads will need addressing later drivers went straight back on passengers fitted ass about eg plug end to coil not pretty but will work for a fire up I'll order some new ones later it'll do for now. 90 degree ends on turbo side and straight on drivers needed.

I need to see if Wideband can output a simulated narrow band signal for ecu to run closed loop, stock ECU Has been flashed to add a datastream from wideband so it can be logged and see live data. Hopefully it can then I don't need my narrowband sensors anymore.

Aftermarket ecu would be nice but the stocker is well and truly cracked and quite the community that shares info.

Well that's everything in the bay I need to make intercooler pipes now leaning towards stainless as I haven't really loved working with alloy so far. 

6 wires to be soldered in to finish wiring ran out of steam (Fucks) to do that today.

Looking like the battery needs to go somewhere else as the Intercooler pipe needs to occupy that space. I could go under it if i get creative.

Blue silicone 90 off throttle body is gross! 

What im stoked with at this stage nothing is a pig to fit it bolts on like factory misses everything it needs too and is serviceable.

Spark plugs won't be fun but also not terrible as most things are vband 20 seconds and the hotside is on the floor.

Crossover pipe in and ready to go actually fits well gave me nightmares almost as much as the damn turbo drain. Feed and return oil lines to turbo also done.

More shit done today. 

Turbo drain welded on.......... in place on the car by someone who can't really weld alloy amazing, it's bloody on there took fucking ages and tools were thrown! But it's on. Tick!

Can see a wideband sensor fitted in downpipe in above photo started installing the unit for that under dash too.

Started some wiring fitted looks mint pity you can't see it for throttle body..... suppose that is the idea. More to do just a bit of soldering to finish off and put in braided sleeve so it can shed heat.

Discovered the ignition coils could flip 180 degrees bolt straight back on and wiring is basically perfect once unwrapped reaches dead easy and won't melt on wastegate, heat shield will be a good idea though.

Airflow meter new location on right side of engine bay set up in photo.
