yes its not to bad if you know how to soider ,the article you read was it by eagle mark? I soidered the socket to the borad so I could close the lid....

I tested all the solenoids except the PCS, will have to dig up a 9V battery for that one, but I did check the resistance between the PCM pins that go...

Values in ohms are: 1-2 shift 21.2 2-3 shift 21.9 Press. Control 4.6 3-2 control 11.4 TCC 23.8 TCC control 11.2 Here's the bench-...

Anthony, you are one generous and great guy! I appreciate the offer to loan me your modified 4288. So, did you soldered in a 28-pin socket? I have...

it may take acouple days iwill get back to you. if you want to program chips or run your autoprom in live mode I have a 288 with the socket changed ...

Hey Anthony, again you come to my rescue. Thanks my friend, I appreciate and accept your offer to burn and send me the PROM. I have new 24-pin PROMs...

Thanks for offering additional insight! I should have mentioned that the case is a 95 K case and the pump does have PWM stamped on it and it was...

You may have a mechanical problem with the PWM valve and bore wear in the valve body. Another issue may be that the PWM (95-newer) transmissions use...

Would it be easier for me to swap to the 7730 ecm or do the inline resistor. The inline resistor interests me as I would like to learn more about it.

They sure look the same, and have the same wiring to them. But just in case, I have a smart ignition driver IC ready to intervene for the bargain...

The LT1 never used a black block PCM. I'm quite positive the OBDII LT1 PCM was unique to that engine the same as the OBDI PCM was. You can swap...

PCM controls the Dwell on a Vortec atleast. Guessing it is the same on a LT1 since I believe atleast the OBD2 LT1s used the same module.

I fished the case connector from the trans up to the engine bay. I'm going through the transmission wiring harness with it out of the car, connected...

Looking at your picture, you can take make a decent guess that TDC will be the leading edge of each low res notch since the leading edges are all...

handyman the autoprom wont burn a chipthat is not electircly arasable I think.if you post the bin you want burned I will burn you one and you can...

Lionel, I did consider the method you mentioned above before I drew up the current design. It would work, but it would take as much as 2 crank...

Here is how PCM interprets opti signal and what it counts. High res signal is counted at every slot full or empty, totalling 720 counts. Low res...

Getting a plan together first is better than going off half cocked with a "solution". But, you've got it all figured out so go ahead. Still, this...

Uploaded again. Holy thread hijack!

I am not so sure the lt-1/vortec ignition module is auto dwell or not. Guess we'll find out. Not one of the most challenging problems ever, you...

I dont think we'll use an lt1 coil, i think the idea was to use the ls1 coil

Did you find anyone to help with the tune? I'm also looking for help

I'd pay about $25 for 8 from the junkyard assuming they'd work with the LT1 PCM. It's loaded with LS engines these days. Sure, the LS coils are...

Not sure if you were talking to me or not. But I do know that the LS coils with the igniter built in are very basic. Hit one with a 5v signal and...

The 2.8 bottem end, specifically crankshaft are pretty much glass. Plenty of stock 2.8s have broken the crank, including the TBI 2.8 in my 1987 S15...

Here is the gearhead pages for the 1227302 http://www.gearhead-efi.com/Fuel-Injection/showthread.php?372-1227302-ECM-Information-3A and the 1227730...

Here's the coil schematic. Looks like it just needs a 5v signal

I wouldn't assume you can use any coil by simply driving it with a transistor. I'm pretty sure the GM ignition modules have current limiting,...
