Lucas 42lb injector tunes please read.

Ok when the GM stage kit tune is on my car it gets the running rich code the pulse width goes past -20 when cruising throwing the rich code. Well the injuctor pulse width is different on the Lucas 42lb injectors from the GM stage kit ones.

We had a intense stage 3 tune and put there fuel paramaters in and now it doesn't throw a rich code but its still arond -10 to -15. So im guessing the Lucas injectors from Intense flow more fuel then the GM ones do.

Does anyone have a modified intense tune so I can look at it and compare it to whats on my car. I don't have HPT my friend does. We are running intense stage 3 fuel setups and his custom timing table from when he got tuned.

I have 2.8" pulley and the 42lb injectors and thats all for mods. I don't have my Intercepter installed right now because the heat in AZ makes the screen fade a lot and I don't want it to break. Doesn't matter if its the sun or covered, it gets to hot inside the car and fades.

Have you checked it lately since you put the stock exhaust back on? It might have brought you closer to 0 since I still have stock exhaust and thats what it was tuned with.

I was running a stage 2 tune with the lucas injectors also... exact same thing happened to me... i got a custom tune from a local guy in denver and it seems to run alot smoother now, i dont get the too ritch code anymore but the is deffinately running a little on the ritch side still...

I think thats because the guy who tuned it has exhaust and its tuned for his setup, im gonna leave it alone for now and see what happens once i get my exhaust on.

I had a 3" exhaust and it didn't matter still ran rich with the GM stage tune.

I have stock exhaust now though. I may throw in the intercepter and monitor it to and from work tommrow if I don't take my bike and see where it's at.
