Testament Posted November 26, 2014 Share Posted November 26, 2014 good work dave, have you seen this http://www.tunerstudio.com/downloads2/2013_MegaMeet-Tuning_with_ScatterPlots.pdf similar type stuff. when you divide maf by rpm you pretty much get map, or maf x dutycycle is going to be the same as MAPxRPM vs dutycycle I wonder if there is a youtube of the actual presentation 1 Link to comment Share on other sites More sharing options...
Roman Posted November 26, 2014 Share Posted November 26, 2014 Aahh true! Nah I havent seen that before, will have a geez later. Man I'd love to get a tunable ECU - But wont be able to for a long time yet. Maybe by next summer. In the meantime I'll have to stick with satisfying my nerdy urges with trying to squeeze some more out of the motor on standard computer haha. It doesnt hurt to learn how things work in the meantime.

kyteler Posted November 26, 2014 Share Posted November 26, 2014 I read it all but i wasn't exactly sure where you ended up in a physical change sense. Are you thinking to return to a full factory air filter box that is uncut but then inlet ducted into the front bar in almost a "ram air" setup? Or are you going to re-pipe the intake completely moving the filter (to pod or otherwise) into the bumper area? I suggest you cast some custom alloy pipe-work that is finned to aid in heat dispersal. How much space is in the air-box/can you dump a stack of ice in there to see the differences of intake temps? Mind you, at ~30° that shit will melt fairly fast. Probably not ideal/waternotsomuchinjection. Link to comment Share on other sites More sharing options...
Roman Posted November 26, 2014 Share Posted November 26, 2014 Are you thinking to return to a full factory air filter box that is uncut but then inlet ducted into the front bar in almost a "ram air" setup? More or less, yeah! So it would pull air from just behind the headlights. Or perhaps have some longer ducting on that far side, if there's an area close by which is naturally at a higher pressure when the car is moving.

kyteler Posted November 29, 2014 Share Posted November 29, 2014 Choice. That's a fair amount of sheet-metal you've removed from that inner guard. Link to comment Share on other sites More sharing options...
Roman Posted November 29, 2014 Share Posted November 29, 2014 I'm pre-empting the rust. Haha Will see if I get in trouble come WOF time. Link to comment Share on other sites More sharing options...
kyteler Posted November 29, 2014 Share Posted November 29, 2014 What's this fandangled ducting you've made look like or is there none really and you've just a hole? 1 Link to comment Share on other sites More sharing options...
Roman Posted November 29, 2014 Share Posted November 29, 2014 Bits of alloy shaped so it's got a forward facing mouth (as currently the inlet hole is at the back of the airbox/ facing the tire) However because I'm a noob I've just realised (via the sound it makes haha) that at full lock turning left the wheel rubs on it because of the caster and wheel offset. D'oh. It Looked like had heaps of room when the wheels are straight / serves me right for not checking. Will fix it up tomorrow In other news though the MAF readings are higher than before (so more air in the motor/ MOAR POWAR!) and it is definitely making power right to redline. My MR2 which had 127kw ATW made max power below 7000rpm, this shows peak power 7350 rpm, just below the 7400rpm cut. So might be over the 130kw mark perhaps / probably as higher drivetrain losses than a transaxle. Either way it's running really well, and cant wait for another trackday to pop up!

cute wee gem Posted November 29, 2014 Share Posted November 29, 2014 Awesome link, Tom. Now I'm gonna go turn lap top on and see how rough my old tunes were. I'd never really used/understood the scatter plots before. 1 Link to comment Share on other sites More sharing options...
cute wee gem Posted November 29, 2014 Share Posted November 29, 2014 Peak power at 7350 must be awesome to drive. So jealous of your rpms Link to comment Share on other sites More sharing options...
Roman Posted November 29, 2014 Share Posted November 29, 2014 Yes and no... its a bit frustrating banging the limiter when it feels like theres more left in it! But even so its great fun banging through the 6 speed with the revs up. Link to comment Share on other sites More sharing options...
sheepers Posted November 29, 2014 Share Posted November 29, 2014 thats some good hole cutting you got done there. i like it. I'm starting to think about how to get some cold air into the blue car and I'm going to have to do some hole cutting myself. Daves cut holes. 2 Link to comment Share on other sites More sharing options...
sheepers Posted November 29, 2014 Share Posted November 29, 2014 oh, and buy a Link. with a good tune it will change it drastically for the better. Link to comment Share on other sites More sharing options...
Roman Posted November 29, 2014 Share Posted November 29, 2014 Ive no doubt youre correct about the link. However ive only got limited car money for the next while, so its pretty much: Trackdays and consumables OR ECU or other spendy bits Trackdays win! I need practice driving more than another 500rpm. 1 Link to comment Share on other sites More sharing options...
