ECUflash ECU Flash

Just posting to see if anyone is in need of help tuning on the black box/ecu flash. I am not claiming to be an expert by any means but I could possibly provide some info. Basically had to learn how to tune this on my own because there is practically zero support and no reputable shop would touch it. I will break down what I have been able to accomplish so far.

Car is a 98 GST
93 pump gas
Full SD conversion
Electronic boost control
FP Green
1200cc injectors
190 pump
Running around 26psi
No oxygen sensors (was having a difficult time getting the ltft dialed in)
-this means car is always in open loop which requires more precision but is doable
No ISC motor (motor went bad and fried that board on my ecu)
-I have been able to get it to idle fairly well
AFR is consistent low 11’s high 10’s no knock
Timing at redline around 14 degrees, peak 8

According to my dragy the car is trapping around 120 so should be making roughly 400hp. Never been on the dyno just street tuned. It runs pretty good. I am sure someone out there could squeeze some more power out of it but the point of this post is to help anyone that may be struggling with this platform.

Any insights would be welcome. As you mentioned there isn't a lot of info.

Is there something specific you have a question about?

I don't but I'm sure even a basic walk through of how you tuned yours would be useful to somebody trying to get started.

Sometimes my role is to just move the discussion along.

Gotcha. I know there are a couple threads on the basics like downloading ceddy mods and what not. I guess this would be aimed at more advanced/nuanced questions.

Whatever you think might be of value. Even if it's compiling references to existing posts for most of it. This is your chance to shine since you offered

I was able to do similar things with mine.
I used an aem wideband to simulate the narrow band and was running e85
