Hi everyone, new to the tuning game. I've got an 67' Jeepster that I'm putting in a LM7 5.3 out of an 06'. I'll need help on the bin file that I'm working on to get it to a manual 5 speed. cant wait to get this thing going. keeping the tuning stock, just a daily driver so it will last. Thanks everyone. glad to be here.:cool:

Often modifying a 4.8 manual .bin or 6.0 manual .bin is a good plan. Unfortunately a factory 5.3 manual .bin is not available. Modifying a 5.3 auto .bin to manual is also a good plan.
I like the plan modifying a 4.8 manual .bin with 5.3 engine parameters.
Ok, so I'm back and it worked. Just like you said. Figured out the neutral safety clutch switch , all good started right up. Now I'm working on the dana300 transfer case manual speedo to digital vss output. I'm finding the correct size but not sure about the ppm. Pulses per mile for the p59 ecu / 5.3l 2005. Dakota digital said 128k ppm. Does that sound right? Anyone know for sure?
They exist in Mexico, just to track one down. They even had manuals in the GMT900 body style down there. 350s in the GMT800s too. There is an OE file for a 250 I6 with TBI for the 7427 that also exist in a ~95 C1500 in Mexico.Quote:

So it looks like we can use any vss pulse sensor. 4k, 8k, 16 k , 128k vss. Yes must be gm compatible thread to your trans/t case. It's all about your numbers you put into your ecm program setup. I did find the higher the pulse rate the more accurate pulses per mile becomes thus the more accurate your Speed.Attachment 19822ometer.
I think a 4K VSS is a very poor option because the Speed Pulse Per Rev number will be extremely low. The 8K VSS already has a low Speed Pulse Per Rev number and is likely the lowest cost option too.Quote:
