I am looking for the Stock running (memcal) PROGRAM for a 80s 350 with TPI with MAF and for a 93 Chevy van running a 16168625/16186695 ECM. The ones you can load into a laptop and run the van from IT and then using TunerPro adjust on the fly. The van is needed now to try and improve both its MPG (10/14) and performance if possible. I hope to switch the 93 Chevy Van from TBI to TPI this winter, which I have two set ups with MAFs, one from a Camaro and the other from a Corvette. These are in storage so cannot get their ECM numbers. And or: Any local Phoenix shop doing these older OBDI systems, and can burn a new chip?? Or any program running the Lean Burn Cruse settings or how to turn them on?? Thanks. Rich Farther information to clear up some misunderstandings: I am trying to do this in stages…first stage as I am CURRENLY running the Stock 93 Chevy Van 5.7 350 computer driving a TBI system, I was trying to improve ITS MPG until we get into cooler temps like out winter this Halloween, then I am considering a TPI with either the original PCM or a 95 LS PCM with its tranny control and better one at a time injector system..and yes I know about opt-spark. Later I plan on getting a 6L80E transmission (Or a 8L90E IF it can be used...)with a control computer for it and a rebuilt rear end with possi and a TALL 2.20:1 gear ratio. Rich

 

Here is a memcal for your 625 ecm , sounds like your looking for a memcal for a 1227165 ecm ?
6e mask has hwy mode but also have vats that needs to be programmed out.
I have a few options if you send me a pm and I can do reprogramming.

Or the newer 8 Speed 8l90e: 6L80E Gear ratios: 1St: 4.484 2nd 2.872 3rd. 1.842 4Th. 1.141 5th. 1.00 6th. 0742 8L90e Gear Ratios… 1st. 4.56 2nd. 2.97 3rd. 208 4th. 1.69 5th. 1.27 6th. 1.00 7th. 0.85 8th.0.65

 

Damn it I hate how this system takes out all spacing and formating,....I had very nice layout for those numbers...as a run on sentence it is a mess. Rich

 

For the oem ecm you should look at pro thread
https://www.thirdgen.org/forums/tpi/...p-305-tbi.html
As far as hwy mode for the factory ecm you should ask tunercat to see if it can be enabled.
Or piggyback the factory ecm with a 165 ecm. The ecm needs a vss signal a Dakota digital sgi-5 might be the answer for that.

"The [code] tag switches to a fixed-width (monospace) font and preserves all spacing"
So you can input [ code ]4L60-E[ /code ] without the spaces and it will display 4L60E without goofing it up.
