I did a serach came up empty. Anyone have a 60# tune. I plan on getting some for mine but want to make sure i have the correct pcm calibrations for them first.

I have a few tunes. You need HP tuners to reprogram the PCM though. Do you have it already?

 

Yup i have it. I just couldnt find anything that sayed how to scale the injectors.

Check the tune repository at HPtuners.com some people have posted their 60lb tunes

 

I checked it and dowloaded 2 of them that were on there. Does just the injector flow rate v kpa have to be changed. Because the battery voltage numbers are differnt also from my gm updated tune?

Any help?

Kyle

 

scale your injectors in flow rate vs kpa, basically multiply by 60/42.5

also you have to adjust for the injectors not having the ability to open at very low pulses. This is only for getting the idling smooth.
I have the data posted on the RL forum:

Final note: when you change your injectors, you mess up your AFR. So now you have to tune your PE.

If your don't have enough knowledge in tuning, buy a tune from TAG Racecraft. This can be a great starting point.

 

Talk to Jim at Tag Racecraft tell him what mods u have and they will make a tune for you for 100$ and they will help you tune as much as they can from the VCM Scanner Logs.

 

Thanks for the help. I have a buddie that does the tuning for me but i wasnt sure about the injector voltage stuff. Usally deal with v-8 stuff and never had to do anything with that table(nor do i think its in there)

Thanks for the help!
