awesome! thanks I am going to test it out. All of these PCM's I have at the moment are junk yard ones I am playing with to learn on. Would My bin off of them be useful for you? Unfortunately I don't...

Hello,
I am messing with an extra PCM I have laying around. It is Serv no 12589463 HDW 12589162 and OS 12592618. It has an AMD AM29F800BB flash. I couldn't find an XDF for tunerpro for the 12592618...

I know this isn't so much a EFI question but I wasnt sure where to post it. I am playing with an Uno v3/MCP2515 module. I am noob when it comes to GMLan or Can-BUS. So far I got it to where I am...

How hard would it be to just mount the tank from the donor truck? ECM needs to be in the cab because it is not water tight. you could use a 1227727 ECM and it is made to be under the hood.

I am using a speed density TPI unit on my s10. I have a 7730 ECU with a NV3500 trans. I wasn't able to find a write up on how to connect this transmissions VSS to the 7730 because the pulse is 40...

I went ahead and went with SST 27sf512 I have the engine running now

on thirdgen it has about 5 posts that even mention the at28c256 some of them say the 28c works but no one says I am using it and non of the posts are using the 7730 ecm so still not sure.

is the AT28c256-15pu compatible? if not does anyone have a list of what is?

I would agree but I dont plan to run the stock computer for a long time. probably about a year. I have really want to build a mega squirt ecu so I am going to. Its $200 for a memcal or $365 for a...

Ok so I have found out I do have to have a VSS signal. I am also starting with the AXXD not AXXB because I am using a manual trans. I have disabled knock sensor by setting 20c, 20d to FF. They are...

Ok so with the knock filter being broken on my memcal I am removing it. Is there anything I need to do the memcal now that I am not going to run a knock sensor. jumper anything? Also with it having a...

I will post some pictures once I start to install the TPI system. I am super stressed at the moment because I cracked my knock filter on my memcal. Its one of the moments you just want to punch a...

Ok my dumb self cracked the knock filter on my AWFY memcal.:mad1: I was removing because I a was scared I would crack it while removing the stock Prom. The knock filter was sitting over the prom just...

Ok so I am starting to work with Tunerpro to make my base tune to get the motor to run. So with the 730 computer I use the $8D and even though the ecu has a AWFY bin I should use the AXXB correct? So...

Ok so I am starting My first EFI build. I am using a TPI unit off a 1991 Firebird formula 305. I am new to EFI but not new to cars and carbs. I've been rebuilding Qjets for about 5 years. But this is...

Glad to hear I made a good choice. I just got home from the junk yard. Got the whole system now. the computers service number is 01227730. I forgot to look for an O2 sensor but I might as well buy a...
