Yes
anything for the 1227730 ECM applies to 1227727 ECM used in 90/91 Vettes
The Vette 1227727 is an under hood/weatherproof version of the 1227730 used in the F Bodies .
ECM pin outs are different but calibrations are the same.

thanks again vetteoz, I appreciate your help!


(we now have two threads... oh well)

mistaben

so using tunerprort (v5)

load an ads file and convert it to an adx file - check.

loan an ecu file and convert it to an xdf file - check.

mistaben

there is a very large number of parameters here... is there a way I can pull what is already on the vehicle using the RT software then change as I see fit?

lets say I wanted to start with just changing the injector size first... then worrying about other stuff such as the change in volumetric efficiency etc.

JackDidley

Just plug the chip into the Burn 2 and click read chip. Then click save buffer to file, then open it.

mistaben

i'll try this... will have to pull the chip out, apart, and put it on the g1 adapter thing first. - right?

JackDidley

That will work. Just plug the chip in. You dont need the G1. .

mistaben

what does ECM pin outs are different mean?

sorry totally a newb at this...

mistaben

dumb question, but is this process the same with the APU1 emulator... ?

so go pull the one out from under my hood right now and plug it in and see what it says?
