New Computor (ECU) for a Early 99

There is more dyno tuning done on them than other PCM's so more power can be squeezed out of the engine. Plus the transmission tuning is much better and is a lot more custom tunable.

samiam- I just bought a PMT2 PCM online for $80 shipped- they had a few others listed but they will have to pull them to see what the program code is. Phone number is 800-477-1367.
If you ever make it south look me up- I'm about 2 hours east of Klamath Falls.

i think the dash hook ups are different for 02~03 so maybe the pcm is different too.
I could be wrong , but personaly i would stick with an 00 or 01....seems like pmt1 &2 work. fwiw i run a pmt2 on my early 99 .

quicker smoother shifts, cruise light now works and I got 1mpg better...no bs.
prob cause of the better shifts...injectors seemed ever so slighty quieter too.

soutmike- you are right, the 02-03 have a different pinout than the 01 and prior. What other mods do you have to your engine besides the PMT2? I can't wait for mine to get here- thought it was here today but it was a false alarm.

[samiam]

Superduty4x4 did you get that PMT2 in there yet? i'm interested to hear your impression of stock differences.

[superduty4x4]

Not yet, still waiting for it to get here. I'll post up once it gets here and I get it in.

A thought occured to me today- I wonder if the new PCM will even work with my truck since it's a Cali model- any thoughts from the gurus?

[strokin_early_99]

What is different with a Cali early99 and a regular early99?

I did not know there was such an animal?

[superduty4x4]

The Cali models have a slightly different fuel system (with bigger injectors maybe?) and a different glow plug setup from what I understand (Cali's use a GPCM instead of a GPR is what I've been told, although I'm yet to find anything resembling a GPCM in my truck. I did throw an SES light from a dead glow plug though, which doesn't normally happen).
Sounds like I probably have nothing to worry about, just a thought that crossed my mind.
