Thread: Lucas 42.5 injector help

I just installed lucas 42.5lb injectors and they are doing great until I get around 90mph then my kr shoots through the roof and the car falls flat on its face. I scaled the Flow Rate vs KPA by taking my new 42.5lb and dividing it by my old 31lb then multiplying the table by 1.37096. I'm not sure if I need to edit any of the other injector tables because I can't really find any information on what needs to be done for these.


Any help would be great.


Here's my current tune, my log and I don't have the WB plugged in because the analog is in another car.

Sorry, edited with new links since my svn wants to act up today.

Dumbass lol

We'll be doing his and mine this week most likely

Yeah I have a wb, does it just need the maf retuned? What about the offset voltages?

Okay ill see if a maf tune helps things. I should have more analogy input on there way this week so all the cars can have one

Hooked the WB up tonight and was idling around 18 afr. Did about 5 maf edits and got it much much closer to where I need to be. WOT still needs more fuel though since I'm only getting to 12.5 afr. And seeing as Duty Cycle is hitting 80% and my Pulse Width is at 19 I might just have to get 60lbers...

Thanks againOH4CompG!

If your mods are current in your signature.. likely you should be checking your fuel pressure.

see derek, told ya it might be time for a new pump :P
