Which ECM are you thinking about learning to program?

I am looking at the gm 122747 in my 95 z-71. I bought a rebuilt 5.7l engine built for a drag car and I was told it had a mild cam, not much more than a towing cam. So I don't know muck about the motor except 4 angle valve job,flat top pistons and the heads were opened up. The problem I am having is ruff Idle not alot of power for what it should be, and not to sure where to put the timming. I havent put to much time into this but I am looking to start to get it all fixed. and help would be great. From what I have read my map sensor is no getting any vacume at Idle due to the cam.

I have been reading other threads and noticed some 4l60e transmission tunning also. I have a 4l60e with a shift kit corvette servo, 12 vane pump and extra friction plates. It shifts really hard from 1-2 empty but loaded its good. I know I am asking alot please help

From what I have read my map sensor is no getting any vacume at Idle due to the cam.Well it should be getting some vacuum but because of cam it is lower, so ECM thinks it under load and adds fuel. There's tons of tricks for this and I can make a 1227747 start and idle just like showroom... of course off idle runs better then showroom.

If you have a 4L60E, then you should have a 16197427 PCM. If you can get the BCC marked on the MEMCAL, more of what you need can be determined.

[pickup man]

This is all great news. the tranny I had done two years ago and still havent broke 5000k on it,my truck don't get driven much. so some of the the things I need to but and do are a bit confusing cause nothing is really together but all here. I would love for the truck to start up and run better than new. what should I do and what will i need? I will get a vacuum reading as soon as I can. I have never done anything with computers and it is not my strong point. but willing to learn. I have called alot of performance shops that tune computers in my area but no one touches these old ones. what is the cost range to do something like this?

[pickup man]

do you know where the bcc is in a truck? I will look for it tonight and get the numbers

[pickup man]

I am sure the computer is a 1227747 but I will look again and open it up and get the numbers.

[dave w]

The 16197427 PCM will have red / blue connectors. The 1227747 ECM will have black connectors. It would be very odd to have a 4L60E without the computer having red / blue connectors.

my truck is very odd. The tranny is 95 only and the engine and engine controls are pre 95. the interior stuff is like 96 and up, but with suttle changes. it can be a pain getting parts. I will look again. I know I need the proper numbers to do what I need. thanks for the help so far everone

[EagleMark]

I thought he had two vehicles? The 4L60E vehicle can't have a 1227747...

[pickup man]

well I made a fool of myself sorry guys. my computer is 16197427. I think I was thinking of my old truck with the 1227747 computer. I should have knowen what was in this truck cause I replaced the computer two years ago. so now that I have the right numbers what else do you need to know?

We all make mistakes. No big deal.

The basics come to mind, memory adapter board, ( https://www.moates.net/g1-memory-adapter-tpi-etc-p-32.html?cPath=64 ) a chip programmer ( https://www.moates.net/burn2-chip-programmer-p-197.html?cPath=64 ) and a chip ( https://www.moates.net/c2-sst-27sf512-chip-p-39.html?cPath=26 ). Software ( http://www.tunerpro.net/downloadApp.htm ) ( http://www.tunerpro.net/downloadBinDefs.htm ) and hardware ( http://www.gearhead-efi.com/Fuel-Injection/showthread.php?1578-Support-The-Forum-Buy-ALDL-Cables!&highlight=aldl+cable ).

Couple hundred mouse clicks and you are good to go.

ok so it looks like $500 plus shipping, do you ship to Canada?

I'm only posting information on the Hardware / Software that can be used for doing your own chips. I'm sure Moates.net (the supplier I posted links to) will ship to Canada.

[pickup man]

ok thanks. I haven't looked into how to do it yet but it looks fairly easy, pop the chip in and test and tune

[Six_Shooter]

Moates ships to Canada, and stands behind his products. I have many of his products.

So I assume all most everyone here has programmed these computers. I know most programs are trial and error but how do you know what peramiters to use? So it all works properly and get the best power an miliage ?

[pickup man]

does moates have the hardware and software to flash computers?

[dave w]

does moates have the hardware and software to flash computers?

Moates sells hardware to flash older car computers (OBDI) that have PROM Chips. Moates also sells hardware to program some of the newer car computers that have "Flash" programming, not PROM Chips. Starting in about 1996 (OBDII) most cars computers have the "Flash" programming type of computers.

PROM programming software (OBDI) can be downloaded here: http://www.tunerpro.net/downloadApp.htm

Ok thanks. I have a buddy with a older 92 ram and he is putting in a newer hemi, the computer is a 01 LT1 corvette OBD2. He is look for something to program it. looks like he can get it here.

Do you know if any one in Ontario Canada is doing the old prom computers? I want to do my own but can't find the time to do so ?

[Six_Shooter]

Where in Ontario?

You can tune a little at a time. It's not like you need to dedicate several hours to tuning, wen you are doing it on your own vehicle(s).

You can simply plug in, start a datalog, and drive to your destination, then save that datalog to review later, when you're having a coffee or sitting in front of the TV, etc. Make the changes that look like they should help, program an EEPROM, and do it all over again.

The only time I need to dedicate tuning time is when I am tuning a fresh install/swap, or I am doing it for someone else, otherwise I just make (mental) note of what I see and what I think needs to be changed, to do later. It helps that I have a display on my dash that plugs into the ALDL port, that displays certain parameters for me to reference.

[pickup man]

Niagara falls Ontario.

[Six_Shooter]

Cool, not too far away, I'm in Brantford.

[pickup man]

I have family in paris near there. Interested in making my chip ?

[EagleMark]

So you gave up the learning how part?

If your just going to buy a chip and Six does not have time PM me.

[pickup man]

No , I still want to learn but my problem Is I use my truck to pull my boat and trailer, It doesnt move much but I work in construction and work most days 16hrs, that dont leave me much time to learn anything properly till the end of december. but I want to drive the truck in the mean time. I had it out on the weekend and at idle it puffs a bit from getting to much fuel. seems to run ok on the hwy but don;t know if it is too lean at that speed and rpm.

[Six_Shooter]

We could possibly work something out. Maybe even just give you some pointers in person on a ride along in the truck.

[pickup man]

Sounds good, we will have to set something up
