Lucas 42.5 injector help

[Dthreap]

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.

Dumbass lol

I just did the same thing with my Bosch green top 42's that I put in. Even with the right IFR table it was silly lean. Do you have a wideband? I needed to maf tune it 5-6 times to dial it in.

 

[MoarkatsINmuhtrailer]

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

 

[Dthreap]

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

 

[OH4CompG]

To be honest I didn't touch the offset voltages. I just put in the modified IFR table and maf tuned it.

 

[Dthreap]

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

 

[Dthreap]

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.

Most scanners read 04+ IPW's incorrectly. You can take a 04+ to like 140-150% IDC with most scanners.

see derek, told ya it might be time for a new pump
yes bill those mods are all current to his car.

Mike you never said such things lol. And thanks for the tip dark.

 

[MoarkatsINmuhtrailer]

or did i?

 

[Dthreap]

That was someone else we know

 

[MoarkatsINmuhtrailer]

that someone also takes pics of themselves after drinking a couple bottles of killians and puts it on facebook?

I'm with this guy. I took my stock injectors to 130% IDC before it started to lean out on the wideband. Also I had the same thing happen when I put my 42.5's in and I'm running a 2 year old 255lph pump

No, broken scanner. The fact its returnless means very little... The regulator is not boost referenced, but it functions the same as a L67 regulator it just does not sit on the motor.
