Hey, i have a jwt turbo ecu right now that i was running on my usdm DE, t28, 3 bar, stock maf and 370cc injectors. it was also programmed for s3 cams. My question is will this ecu work still with my det swap, same injectors, t25, same maf, but no cams? TIA

Yes it will work. May have soem differences but, it will work.

It will have a non aggressive timing curve for the low compression motor. You may want to run run a little more base timing and see how it feels. Since the MAF and the injectors are the same it will most definately work. Make sure to use USDM sensors and not the JDM sensors when you do the swap.

I run 16 degrees base timing with my JWT ECU programmed for 9.5:1 on my BB motor. No problems on 12lbs of boost. I also sent you 2 more PM's if you got them.

If it matters I also gap my plugs around .32.

It is high, but this JWT computer is crazy rich. It runs like a raped ape though. .28-.30 is usually normal.

i'm having mine re-done right now for the 8.5:1 DET engine. i was running the 9.5:1 program for a while and yes it ran fine. with my old set-up i would start to ping at 12psi on 93 gas, with the lower compression i ran 14-15psi with no pinging! but you could tell it was more sluggish at lower rpm's. hopefully the re-program will help. JWT said not to advance base timing to try to make up for it. (said may have too much timing at different rpm's) i was running 16-17* anyways, ran fine. i would like to dyno after the re-program to compare.
