Delco Based 1991 Isuzu Impulse RS

[90base]

Hello,

I make a thread a while back (long while) https://pcmhacking.net/forums/viewto ... 590#p32569 about my Geo Storm running Isuzu Impulse RS Management with a Boosted Impulse engine and was interested in doing some tinkering with TunerPro.

Well I finally got a Moates BURN 2 and managed to pull the bin file off of the chip, VL400 and another guy said they could help me once I had a good bin read. Can anyone help me out? I found an ADX file for the LOTUS ELAN M100 which has the same engine and ecm confiugraion along with most of the sensors.

Some Information

ACDELCO Part # 88999205 {#16142013}

Awesome! I'll give it a shot tomorrow. I've been told it looks like a B4 Mask ID. I appreciate all your help! I'll update when I figure out some more.

yeah if the program id bit is in the same spot as our tunes its B4 which you will have to change to AA so it doesnt checksum the bin if you make any changes.cant remember if that xdf had conversion equations this one does so spark and ve should show real numbers i hope.if you can log data you could change the spark table values all to a figure and flash a timing light on it to confirm it is spark table same with ve table change a chunk near idle and see if it gets richer and start tweaking where needed spark and ve changes should get you a long way started getting some power
