Carl Posted March 31, 2019 Share Posted March 31, 2019 Hi Would anyone have any known good Bosch 980cc data pn 0 280 158 040 to be used as a starting point? I have tried race worx data. Having some trouble atm, Lambda vs Targeted Lambda is pretty much spot on except when you load it up hard for a short period of time it will hit the Targeted Lambda as required and then a few seconds later will richen right up. If just doing a pull from standstill it will hit Target Lambda in 1st and 2nd but when it goes into 3rd(top gear TH400) it will hit Target Lambda and then shortly after will richen right up again. Doesnt seem like injector data is wrong as it is targeting fine except for extended periods at WOT, is there any fuel multipliers that could be causing this when under more load in top gear? The engine is fitted with all the normal bolt one. valve springs, head studs, forward facing plenum, gt42r turbo, oil pump gears, Fuel system. Turbosmart fpr1200 fuel reg, two race worx 044 pumps in surge tank and a holly blue lift pump. Could this be a speed density problem? And if so how would be the best way to approach it.

Sam Posted March 31, 2019 Share Posted March 31, 2019 How rich is it going? Quote Link to comment Share on other sites More sharing options...
Carl Posted March 31, 2019 Author Share Posted March 31, 2019 I have a target of 11.6 and it will go anywhere 10.3 / 9.9 Quote Link to comment Share on other sites More sharing options...
Sam Posted March 31, 2019 Share Posted March 31, 2019 (edited) There is some fuel enrichment for exhaust overtemp, cat protection etc that might be causing this. There is a little write up showing these table. Have you played with those fuel enrichment tables? Edited March 31, 2019 by Sam 3 Quote Link to comment Share on other sites More sharing options...
Carl Posted March 31, 2019 Author Share Posted March 31, 2019 I haven't tried that yet Quote Link to comment Share on other sites More sharing options...
Sam Posted March 31, 2019 Share Posted March 31, 2019 Have a play around with those fuel enrichment tables and see what you can figure out. Let us know how you go. Quote Link to comment Share on other sites More sharing options...

Carl Posted April 7, 2019 Author Share Posted April 7, 2019 (edited) Ok I have tried playing with all the turbo protection settings and it still goes rich Iam starting to think it is the injector data cause it goes lean coming on to boost then rich on boost with a target of .80 across the board. I have tried following the how to injector scaling with no luck I think. On decell it's rich (13.2 afr) i have tried raising and lowering the deadtime and injector pw. Cruise is (14.6 afr). Coming on to boost its (15.6 afr) right up to about 5psi of boost then it will hit target then go rich a short time after i have tried moving the breakepoint and hi slope. I'm not sure if I'm just a dumb ass or what Edited April 7, 2019 by Carl Quote Link to comment Share on other sites More sharing options...

BFWAGON Posted April 10, 2019 Share Posted April 10, 2019 Hi Puffwagon would it be possible for me to grab your bosch 980 injector data aswell cheers chris Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted April 10, 2019 Share Posted April 10, 2019 I'll just leave it here for anyone to use. Bear in mind that all cars are slightly different and you need to double check the tune with a wideband. I left the low slope slightly rich as it starts much better like that when it's freezing cold. Feel free to raise the low slope to 120 (less fuel) if you feel like it. Bosch 980cc injector parameters.param 4 Quote Link to comment Share on other sites More sharing options...

You click "import from parameter file" from the "file" dropdown at the top left of the screen, when you're running the pcmtec program.
