got 99 gtp w/91000 on her just got done doing mods to her and she seems to run alot better , BETTER THAN BEFORE BY A LONG SHOT,what did was 3.25 pulley/ported man headers/cai/hi-flow cat/u-bend delete/super44s/no resistor/180 t-stat/ngk155s i think? they are two heat ranges colder/the only thing i have not done was the pcm....... i know iknow that should of been the first thing but forgot.... my ? is a guy down the road as the same car same everthing... he has a pcm from zzp 1.0 will it work in my car??????????:banghe ad:

the 1.0 ecu upgrade is more for lightly moded gtp's cold air intake,u-bed delete mufflers a 3.6 pully ect the little things.since ur running ported heads and a 3.25 ur gunna want to get the 2.0 ecu try www.3800preformance.com i get my parts from them.i hope u did u-bend delete though or that'll be another big uhoh

Thats funny. I had no issues running a DHP v1.0 PCM with a 3.25" SC pulley, of course with supporting mods. I now have a custom programmed Intense. These v1.0 PCMs are programmed to go as low as 3.20-3.25" on SC pulleys. Check the specs at the link you provided at 3800Performance which has a typo.

No issues here either (check mods in sig). I was running a 1.0 for a while but I have never went any lower than a 3.4 pulley.

Maybe he should look into a powertuner (for the cost of a PCM with 2.0 bin on it).

now the ? is what is KR and do i have it? and how do i know? and the mods i did will it make it better/worst? and if i do have it what does it sound like? and how do i get rid of it? and will the pcm from another gtp same year same everthing work in my car ? he only wants 50$ for it....and i was wrong on the pulley its a 3.4

KR = knock retard.

doctor, you don't have to be rude and call him a retard, it's a valid question...

Just kidding, KR (knock retard) is created when the PCM detects knock often caused by pre-ignition, and retards timing to try to eliminate it. This situation will be amplified by running a smaller pulley (and your other mods) due to the increased boost.
KR reduces performance and is an indicator that there is a possible problem that could cause engine damage if not rectified.

Lastly, with the mods you're talking, don't even think about running less than 91 octane.

so how do i know if i have it? can i hear it? and with the mods ive done did i make it worse? and ive always ran 93 up to 110 octane... and im still yrying to get a answer about the pcm?

KR monitoring software is the best way to monitor it

Pre-ignition knock/ping is a "marbles in a coffee can" type of sound you may hear during hard accelleration.

You may or may not have any knock or KR, it all depends on your combination. Ideally, you want 0 knock and 0 KR. Monitoring software like a scan tool, power programmer or auto-tap would be helpful.

did you read posts 2-4? You have 3 answers right there. Post 2 and 4 stated that a 1.0 may not be optimal for your setup, and suggested a more aggressive tuning option. Post 3 says it will work and even gives you a like to a website referencing it.
