Hey guys, haven't posted in awhile. Been busy with work, school, etc.
Ever since installing the 749 and injection, my Dodge hasn't quite run right. No bottom end torque and pinging in half of the...

I finally got the pickup running decently, turned out the o2 sensor wasn't working. Hard to diagnose, tunerpro always said it was sitting at 448 MV, even with no sensor hooked up! I could get it to...

I have no idea what it is called, my uses the stuff at work to dissolve potting material. He just calls it solvent, the can didn't even say the name!

Thanks for the offer billy, but we found the problem. After soaking the whole board in a solution to take off the conformal coating, we found about 6 broken solder joints on one chip! A little...

Honestly I didn't even realize we had one! Lets see if I can afford an ecm then!

That would make sense, the clear coat is flaking apart, plus I can sometimes get It to work by pushing on the chip carrier. Can it be cleaned and reflowed? I dont have a good source for amother ecm...

I would, but I don't have another laying around

Its a 1227749 ecm out of a 90' sunbird turbo, using 27sf512 chips. It seems to start working if I push on the whole carrier, not sure what the heck could be the problem after thourily cleaning it...

My ecm is intermittent, it will run perfectly fine for a few minutes, then suddenly go bonkers, dumping a ton of fuel in missing alot, the check engine light starts flashing on randomly and once the...

Ah, that is basically the same chip in a DIP format. I only question the PLCC32 variant due to it's availability and cost, plus ease of finding a programmer!

do you use a 28 or 32 pin adapter on that? And for that matter, tell us about it! How do you install it, what direction?
This sounds like it could be a good lead, at least for my uses.

Hey guys, I've been doing some hunting online and came across something interesting. Everyone that has tried burning chips knows our beloved SST 27SF512 is not readily available, people are even...

As for weatherproofing you could always either pot the computer or even put it in some kind of case. Really so long as the thrings outta a splash zone it should be alright, unless you plan to do some...

That's what I had been thinking, although the other one looks easier to plumb. but thats a one-time ordeal anyhow!

Hello all, quick question
does anybody know the differences between the different Rochester single barrel TBI setups? I know there are the 2 different styles, the 300/500 like used on crossfire and...

Problem solved! A friend of mine has a bunch of the old 80's cars with em, My only issue so far is picking a throttle body to use, Rochester 700 or 300/500?

I honestly don't have too many pics, but I'l try!
Here's some pics of the truck itself, plus a few of the turbo setup....

Hello all,
The name is Josh, I drive a 53' Dodge pickup. I bought it from the original owner at the age of 15, and my dad and I built the thing together. Now 5 years later it actually is my daily...
