Just put mine in this morning and it seems to pull alittle harder. not a big difference in shift firmness. Tow/Haul does make a difference. Seems better than my HPIII, I heard it will get better with more driving. Hope so! Anybody got this tune and the SES light did not come on? I was told that i should be getting the relearn code but I am getting nothing and I have driven over 50 miles already. Any suggestions? The Clinton manual says that when ever you change out the PCM you should have it done.

 

i have read where you should do it no matter if you get the ses light or not.

 

ok what about when you swap a motor out??

 

i haven't heard of doing it for swapping motors out. With as many people around here doing engine swaps i am sure there would be some expert advice on it though

 

ive got a PCMforless tune, didnt feel like waiting until Christmas for Jesse to get me a tune...no offense, he's just a busy man, and i hate waiting on anything.

the only thing i had to do was the security relearn. the truck wouldnt start...well it would light off, but then die immediately.

as far as any other relearn i dont know. mine runs great, hauls ***, even though its setting a code for the MAP sensor, lol.

Jesse said to get it done when putting a new pcm in, even if you dont get a light.

 

I will be taking mine next week to get the crank relearn. I did not get a light.

 

I called Jesse and he told me to get it done anyway. Called the dealer and they said $75. For 5 minutes of work, I couldn't believe it! Anyone in the Gulfport, MS area with a hook up?

 

Needs a case relearn, it's the same as if you just swapped the PCM.

The PCM needs to know the relationship of the crankshaft to the cam via the crankshaft pick-up sensor.

if you replace the timing chain, timing gears it will also need to be redone.

 

isn't that the one where you have to rev your eng to fuel cut and back down if it is shouldn't i wait till the break in is good before i do that or will it be ok?
