Found a problem.... Coolant spark was cutting 10+ degrees at normal operating temp. Got the INT and BLMs sqaured away too. The WB02 spreadsheet is awesome. At first I didn't think it worked as it...

So after installing an LC-2 WB, my BLMs are no longer updating. The INT value changes, but the BLM does not change in closed loop. Not sure what to look at.

I was planning to do that. Ordered a WBO2 today, and the pin tools.

Thank you for the response. I will read through it.

Although I have been a mostly inactive member for a few years here. I don't think I ever posted an introduction.

I was referred to GearHead-EFI by a friend aware of my hatred of carburetors and...

I know my injector size is off. I am waiting for a fuel pressure gauge to show up in the mail so I can get an accurate fuel pressure measurement. I am using 454 81/lb @ 12 psi injectors in a 454 TB...

I am at a loss on this one. I have effectively, as far as I can tell, disabled PE for tuning purposes. However, it still activates and throws off my logs. I remember there being more to disabling PE...

Turns out it was a bad HID bulb. Was still lighting, but one insulator cracked near the base of the bulb allowing it to arc across and backfeed through the ballast. Was causing a good voltage spike...

So I had something odd happen... Hope someone might have an idea. I added a relay at the headlight dimmer switch to keep my low beams on with the high beams. I am running HID bulbs with ballasts for...

Drove almost 1000 miles and towed a car home with it! No issues, other than it being really hot in Las Vegas. I will post a copy of the bin in a day or so.

Well I found the root of my problem.... At some point my dist hold down loosened, guess what base timing was wayyy off. Explains chasing my tail with the VE table the last few hours. Glad it wasn't...

I feel stupid asking this, but where is the VE table? I have gone through everything in the XDF and have not found a VE table. I know I had one in my $42 XDF. Nevermind, I found it.

Have yet to do any VE tuning. I was hoping to avoid the need by using a stock TBI 5.7 L05. The pump IIRC was a 3902, I swapped the first one for an AC Delco pump, didn't make any difference. What...

Got an ostrich from Moates! Had a chance to play around with it a little today when I got home from work and got a small log saved. Still pretty overwhelmed with this project. Played with the spark...

Installed a ZIF socket to a 5.7 memcal. Makes prom swapping sooo much easier. Took a bit of finesse to solder in the socket, but it works! Tried disabling knock retard to at least eliminate a...

Applying 12V directly to injectors for bench testing and cleaning for short periods of time (60 secs or less) has never caused a problem for me. That aside, I finally got a usb ALDL cable.
Drove...

Yes I have Tunerpro, just have to wait till I have days off to mess with it again.

I checked for the 12V+ at the injectors. No problems there. The 8625 isn't providing the ground, but the 7427 does. Not sure what to make of it yet. I will play with it more on my next days off.

So I put my memcal with the BJYN code into the 7427 ecm, and after getting my timing sorted out, it fired right up and runs great. Only problem is that the 7427 ecm is throwing A/T codes at me. The...

Ok, so I have it together and ran into a problem. The 8625 ECM is not firing the injectors. I swapped the ign module with a known good one, and checked all my grounds to the ecm. I can give the...

That is great to hear! That is my plan for it. Found a BJYN bin and got it burned and resoldered to a V8 memcal. Fingers crossed. Still have more to do to the truck before I can even fire the engine....

Well, I have some days off and time to play with this some more. I got a complete harness and 7747 ecm from an industrial 5.7 m/t truck, but that will be used for something else down the road. I...

Found the info I was looking for and saved copies to my phone. Going to Vegas in the AM to pull an ecm/harness and a flywheel. Still waiting on a lot of parts in the mail. I am as far along on this...

Thank you! This will help a ton while I'm at the bone yard.

I still can't get BCC find to work. Is something wrong with it? Trying to find info on BDUJ

That is why I will gladly swap to a 5.7/MG5 ecm and harness. I want whoever ends up with the truck to be able to goto any shop and get it worked on without issue. Thus the reason I want to use stock...
