How to Control a 4l80E with a GM 16197427 ECM

http://mattw.dyndns.org/4L80E/

Friend of mine has a 06 he said he'll give me. Is this something I can use or is there a cut off on the years I can control with the 7427 ecu

[MxRace75]

I picked up a 2004 4l80e with convertor last night.

Would I be better running a 16196395 ecu since that's what came in the 94-95 350tbi trucks with a 4l80e or will the 16197427 work just fine. I have a 7427 ecu I just need the Eprom for it. Already have the moates adapter and a apu1

No difference in those PCMs, either one will run $OD $OE $E6 or $31.

[MxRace75]

Cool. Does it matter what eprom I buy to work with the adapter? Like does it have to be of the same base bin I plan on using??

[MxRace75]

Where did all my helpers go?? :-)

TPS I used a alum plate mounted the TPS sensor and an extension arm to the paddle

I have a diesel throttle pedal / APP sensor and TCM here. I thought it would be easy enough to weld an extension on the pedal to attach a cable but I haven't yet done a stand alone 4L80E install.

That sounds like a neat setup.

I've never seen TP files for the TCM, either. Options are Tunercat or one of the TC resellers.

Years ago I helped a guy building a custom efi system. We used an electronic Q-jet for the throttle body. Machined the venturis out and used the TPS to a 165. The engine had vacuum hoses and wires all over and a quick glance left you thinking it was a carbed engine in full emissions gear.

XDF files are user made and we've only got so much information available to make them.

TC author was involved with GM engineer early on to make custom cals, branched out into his own software. Early work involved disassembling but not sure where OBDII info came from. I don't know what's present or missing in TCM files but I've never had trouble getting anything added if it really exists in the cal. What's wrong with the OBDII files?
