Default Will a 02 pcm work with a 99 harness?

What's going to be the difference. I cut all the extra I don't need out of the harness already. That's the rear o2s,egr,ac,all the auto tranny wires. All I have is the engine harness. What is going to be the problem with trying to run this pcm? I have a vats bypass. I'm just wondering if the motor will run right. With everything pluged correctly in. Thanks.

Yes. Now if it was 98 then youd have issues, Srun. You may have some pinouts in the wrong location and a tach might now work but i think you could figure that out by removing that pin and switching it to the right hole its supposed to be in.

yes it will... but you'll want the OS flashed to your year (or the tables that are different modified) ... biggest thing is the injectors are different between 99 and 02

Id personally stick with the 02 tune....99 and 02 the injectors were the same or right about hte same size of 26/lber's

98, 01, 02 = 28 lb/hr (I think 28.8?)
99, 00 = 26lb/hr (I think 26.4 or so?)

The 02 OS is nice for SD tuning though (no need for secondary VE)

You seem pretty knowledgeable....Let me pick your brain..hahah

I have 42 lb/hr Green tops in my car. I need to use one value for my IFR table since ive gone to a vaccum regulated setup. Ive figured out that they are truly 48.78/lb/hr injectors at our 4 bar fuel pressures...

Now in LS1 edit How would i convert that to a usable number that i can enter across the entire table of numbers?

Then just flash the 02 to a 99 flash....Its the simplest way.
