P59 PCM.......does it work all systems normally
P59 PCM.......does it work all systems normally So, I searched a bunch but can't find an answer.
I want to use the P59 PCM so I can tune using a Flex-Fuel sensor.
Question: Its a 1998 Trans Am......will the P59 PCM work all of my 1998 engine harness sensors, 4L80E thats going in and all of the gauges in my gauge cluster normally?
Thanks.

Yes but it needs a lot of wiring changes
I have converted several fbodies and vettes to 411 PCM which is mostly the same and works good.
If you are not comfortable doing electrical work and using wiring diagrams, don't even attempt it.

It will work with a re-pin. Tach will need a pull up resistor, your fuel gauge won't work will have to get an after market gauge. Also change the O2s to new style white connector they work better. I have a 98 that swapped to a P59 PCM.
How about all the engine sensors (IAC, TPS, IAT, Temp sensor, Crank and Cam sensor, etc.)
Do they all work fine.....
I want to use a Flex-Fuel sensor so I can run any type of fuel without worrying about changing tunes.
I wonder if its easier just to use an 99-02 0411 PCM.

But I'd like to use the P59 for the Flex-Fuel sensor so the tuning is easier.
But man....I don't want to lose my gas gauge.

If I was in your place I'd use a 0411 PCM to have everything work including flex fuel, gas gauge and transmission.
Its gonna be a near 1,000 RWHP set up with single turbo around 18-20psi......can the 0411 easily handle that for easy tuning??

Yes 0411 can be used for flex but are limited to 2 bar and flex. But if you're going to go through all the trouble to repin for a 411 might as well do it p59 best PCM you can get and it supports 3 bar and flex which seems to be the best for you if you plan to reach a thousand on a stock computer. Yes you will have to get an aftermarket gas gauge. Even with a 411 you still have to do a segment swap which may or may not work.

Can you tell me this: I bought a Frost plug-n-play wiring harness so my 4L80E can be operated by my 1998 PCM with just a segment swap in my PCM.
Do you know if that same wiring harness should be used with the P59 PCM to operate my 4L80E? My tuner will be re-pinning my factory harness to work with the P59 PCM.
I asked Steve at Frost and he was not sure and said to leave that up to my tuner to figure out how to make it work with the P59.
And...can the P59 go 3 bar, I want to push 20psi of boost?
Thanks....

Thanks.....thats a relief.

IMO I would ditch that junk and wire the transmission up like it would be in a factory truck/van and then segment swap a true 80E tune into yours so that the control logic is correct entirely and not hacked.
