NX2000 ecu for SR20DET (370cc, Z32MAF)

Hi everybody

I just want to share with this forum those files for those of you who want to run the stock NX2000 ecu with your SR20DET

The NX2000 file have been tested up to 17psi and it's running very good
Forged SR20DET
T25
370cc injectors

I have some 240sx tuned rom too if someone want them
The file with the 750cc injectors was running with a T3/T4 and at 24psi it develop 355WHP. It has not been wideband tuning so you can fine tune it. The other file with 550cc injectors was with a T28 turbo.

Thanks
Fred

Have you tested the 550cc with the Z32 MAF combo?? I noticed that Live Edit does the exact calculations that you have. Some more info would help

I'm from Canada and have sell this daughterboard to someone in Florida and he said me that his cars run very good but i didn't test it myself

I made this file with Liveedit and it seems that Liveedit put a Kvalue that make run the car leaner than if i do the math by myself. The 750cc have been done with RomEditor

Thanks
Fred

Hey Fred, is "91nx2000 (370cc stockmaf, turbo bin.).bin" a tuned bin ? What size turbo was run on it ? EGR removed ? Rev limit ? Currently, I'm running JRIOS's US_DET.bin on my NX, it works fine but it is not tuned, just fuel & timing maps copied over from U12 program.

Hi
This car has not been wideband tune yet but it runs good, don't have any hesitation, run rich. It's for a SR20DET that is forged one but with a stock T25 turbo, Rev limit was keeping low because the car was in is break in period but it can be adjust very easily. I retard the timing to be more safe for the break in but when i will tune it with the wideband and my knock sensor monitoring i will advance it at maximum before to have detonation. I have expanded the map, make it run richer and adjust the K value and stuff like that, to run with the 370cc injectors. Just give it a try to see if it's better than yours!!!!!!!!

Hey, does it matter if the 750cc injectors are low impedance?
