Actually now that I think about it, he said he replaced the computer and the current computer running it is a 7427 with the bjyl prom. Its a 93 and I'm not sure what computer came out of it.

Im trying to help a guy out with a tune for his truck and need advice on a starter bin. I haven't touched this stuff in a couple years and im pretty rusty on it. He says its a z71 350 bored 40 over...

I have many items for sale, Both ECM's are modded to install burned chips, I have a programmer I can sell too but in only works on windows 7, had no issues burning chips with it. Also I have a moates...
The intake is an edlebrock along with a 350 TBI and I believe 61lb injectors. I have them running at 20psi and have the bin adjusted to them. The spray pattern looks good too.
I have the bin set...
I have electrical testing tools, no feeler gauges but i can pick some up. Also the napkin gets sucked into the exhaust tip, I actually thought I lost it until it shot back out. The truck has always...
As the title says, is it normal for exhaust to suck air?
Some background iv got a stock 350 vortec crate engine from jegs with a tbi and a 7427 computer controlling it along with true dual 2.5...
It's alive!! so the brand new acdelco ICM completely died. I had an old one laying around and finally had time to hook it up, well it fired up no hesitation.
Thank you guys for your help with...
I read a way to test the pickup coil on the distributor. The test said to put the DMM leads on the plug for the pickup coil and have it set to AC and have someone crank it. The page said it should...
I did test power going into the coil but I did not test power going to the ICM. The pink wire did have 12v going to the coil. I also tested the wires coming from the coil to the ICM and they test...
I just tested to see if it would fire while adding fuel and it didnt even try to start, will a bad coil prevent the injectors from firing or did my new ICM already go bad? I have another laying...
It's an acdelco I bought from Rock auto, it does have a warranty option so if it's bad, I'll be using that.
I have another ICM that Hopefully works along with thermal compound I use to build computers. Is it the heat that kills them or other factors along with heat?
So if it does fire up with fuel added manually, where do I look next?
I failed to mention this is a TBI, Its a 7427 computer controlling it all. I recently redid the fuel system to include metal lines and fittings on most all of the fuel system and an adjustable FPR...
I actually have not tested if it will run with fuel or not.
As far as the noid light, correct me if im wrong, but if the noid light flashes properly when turning over, that means the PCM is...
I have not had the chance to get a noid light yet but I did three other test.
First, I used a 9v battery on the injectors and both sprayed fuel no problem with the fuel pump running. So that must...
I should have said pigtails or whatever you want to call it. It's just the 2 new plugs that go to the coil with wires about 6 inches long I had to connect to the existing harness, I tested them with...
So a while ago my injectors quit firing, after researching, I rebuilt the distributor with a new cap, rotor and ICM. After that everything was running well for a while until it started again. Well I...
With all these numbers I think Im going to set my gauge to use lambda instead to make it simpler, well hopefully.
Side thought, if i log the lambda and its off 10% from what i want, would I...
Awesome, thank you,now to start seeing how it goes.
you say multiply it, what if it were at 13:1 when its supposed to be 14:1 does it still go 13/14=.929 then multiply that cell? or is this...
Forgive me as im fairly new to this. When you say log the wideband, will that be with the logging software the WB came with or the numbers in TP since I have the WB connected to the PCM.
In my Open...
A small update, I set my WB back to 14.7 to see if the XDF will show proper readings and its around +/- .5. Not sure if it was intended to be exact or not.
Also had the simulated NB going at at...
First im running a 7427 on my s10 with a stock 5.7. For the files, I use the Advanced $0D TP5 v251.xdf and the BJYL 350 TBI 700r4.bin along with the MTX-l WBO2 sensor.
1st o2 question: I followed...
Good to hear you got it running! I thought i had fixed my exhaust leak but its still acting up so i may leave the o2 out since it seems to run much better all around.
