It was a rebuilt trans. Don?t know much about the internals unfortunately. The torque converter is a Hughes 2000 stall. The 1-2 is pretty firm, 2-3 is firm. 3-4 feels like a hammer hit. I?ll try and...

I have a friend of mine that I am trying to help out. I don't normally mess with Transmission shift points or anything because i don't know enough about it to do it properly. My buddy has this GMT800...

There are a few good videos on you tube. A few things to set first. 1. fuel injector flow rate. Depending on the throttle body it might need some work to the idle air valve.

Check out this video...

Yes, It was my mistake. I was thinking it would work but this regulator is made to run after the rails not before and i am running a stock ls truck rail so I am stuck with a single inlet. Now i Need...

Well, I think it might just be a bad setup on my part but now I don't know. I have a quantum 340LPH in tank pump and a Holley 12-880 Fuel pressure regulator. Its allowing the fuel to go back in the...

Well I finally broke down and dug through my storage unit for my Fuel pressure gauge. Looks like i have a mechanical issue. Maybe a leaking injector???? It primes but immediately loses prime. and no...

I have a 99 Suburban that I have ls swapped and it had a gen3 6.0 in it. It never fired up super fast, normally takes about 5-6 seconds to fire. Sometimes i have to turn the key off and let it prime...

Ok, I figured it out. My pids were set up to run a v engine with 2 banks. This being an in-line motor it was only one bank and it was averaging the 2

So I am working on my Father in laws Chevrolet Colorado. I had to do brakes on it and saw the SES light was on so I decided to hook up to it and see what it was. The codes were P018 b and C Fuel...

I have a BTR stage 2 Truck cam and I added 2 degrees timing to my starting spark table and that helped a lot. I was also overfueling on my cranking fuel so I cut that down by 15% not sure if that is...

I think I have the misfires figured out, I think I am just being hyper sensitive since its a new motor. I actually replaced the knock sensor wiring harness and the sensors, I think this was just a...

I actually went digging and found that #1 Cyl plug wire wasn't fully seat went and did a drive this morning and it still was showing a bunch of misfires under the history for #1 ( a lot more than the...

I am currently logging Misfire current cylinders 1-8 as well as total misfires. I attached my log and can see where the misfire count goes up occasionally but cant tell if its normal or not. I feel...

I am running a quantum 340lph fuel pump with a Holley fpr. My fuel pressure is set to 60 at the rail. The only other problem I am having is hard starting sometimes from the engine flooding. I took...

I am using an aem wideband logging through the egr. I did realize today though that I had the stft still on and wasn?t set to 284 so I am gonna have to work at it this weekend with some longer drives.

Maybe someone else has a better idea, any chance you got the cam and crank off time when you swapped it out?

my mistake, I have mine set to 30 instead of 33 since I only have 50psi at the rail. I was looking at my file for a compare. holding the throttle at 100 percent shuts off the injector (flood clear)...

Is it backfiring in the exhaust at all? I had to take a ton of fuel out of my cranking ve as well as took out some of the mutiplier for the cranking fuel tab. you need to scale your injectors...

out of curiosity did you segment swap with the same year trans segment and confirm the OS's were the same?

So I am not good at this at all. I am still learning. But I did notice when your KR kicks in the Throttle position is matched with it so it does seem to happen when your map starts to climb. Out of...

Can anyone give some insight into if i need to continue to smooth the map or if it is ok, I am within a 5% error on the log. I havent gotten the truck into higher RPM yet, I have only been able to...

You just saved me a ton of work. I thought for sure my TCC was locking up causing a bog and running like crap. Once I realized it was not that I went back to the basics. I had a dead cylinder from a...

So for anyone who has this issue in the future, there are 2 channels to log, one is TCC applied and TCC MODE. The TCC MODE is the one that logs the on and off.

I posted this in he gen3 tuning nad havent gotten any responses from that forum so I figure since its trans related I would post it up here.

I have a 99 suburban I put a 6.0 ls in. I kept the...

This might need to go in the transmission forum and if it needs to be move let me know. I have a 99 suburban I put a 6.0 ls in. I kept the original trans in the truck. The pcm has an 02 2500...
