Re: Retarded Ignition

Could you not just offset (retard) the CAS sensor then add the positive spark offset in all necessary maps so you could achieve a actual negative spark timing? Or is there code somewhere that would not be covered by this and cause problems at some point with too much retard??

Re: Dwell time/length

I don't get this problem on my 32 ecu using FP firmware at least if I just raise the rpm in neutral. Targeted 3ms and its pretty consistent up to 6krpm. Sometimes I get a random 1ms or 4ms (dangerous with my GM D585 coils!) in map tracing but when it goes back over that cell its around 3ms. Be inter...

R35 Injector latency

As title does anybody have injector latency values? Im on feature pack 2 so a table is easier but I can convert from non-FP system if anybody has tested/calibrated them.

Does haltech etc have any values in some basemap I could rob them from?

5v supply r32 gtr ecu

I am trying to get map sensor values into consult using a techedge 3b1 which will send the sensor data over the serial connection. I need a 5v source to run the map/boost sensor which is the best one to use for the 32 gtr ecu. I was thinking TPS as its close to where the sensor will be? Is the power...

Re: Auto rescaling not just scalers but also maps

R32 GTR ECU will halve the VQ maps becuase there are two MAF inputs, so that is normal. You will will need to adjust K constant until you get full usage of the map But it had 2 Z32 mafs swapped to 2 gtr slot style mafs. If you did a calibration compare the maf curves for the new GTR slot curves wer...

Re: R35 MAF for R32 GTR. How to arrange in engine compartment

I guess from your other post your sorted this but I used these for reference if anyone else needs ideas.

Not cheap but a direct fit using existing pipework if thats what you want.

Re: Auto rescaling not just scalers but also maps

At this point I would like to run the car on the dyno and check actual figures compared to theoretics due to the variables including the non-linear curves the MAF uses which cannot be calculated without introducing polynomials, air dynamics and pressure into the equations Did you get time to do thi...
