Intense PCM.....Has Problems

I love the intense PCM...most of the time....The car still has an idle problem, not as bad as stock but its still there sometimes, But its not that big of a deal. My biggist problem with the PCM is when im WOT some times the car loses complete power for a split second almost like a hick up. And the other day when i was driving around my car wanted to die when i let off the gas (it stalled twice on me). I asume it was flooding its self cause it used almost a half tank to drive 8-10miles home, I let it sit for the rest of the day and started it the next morning and it was fine? Has any one els experienced this with the intense PCM?

My car also experienced a hiccup problem where I lost complete power, but this was after I switched pulley sizes with the intense pcm. I disconnected the cable from the negative battery terminal and let it sit for 10 minutes to reset the pcm and then let the car idle for 10 minutes and the problem was fixed.

I get that hicup with Stage 2 reflash and had it when I was on the stock PCM flash and never found out what makes this happen.

Not sure exactly what letting the car idle after resetting the pcm does. I was just told that it was part of the procedure to do after installing new mods that affect airflow so the car can learn the new mods faster.

Get your car on a dyno and check out whats happening. If you have an aftermarket intake installed, its probably messing up your MAFT tables. It happened on my car, and i had to have my pcm tuned for my mods. Just a hunch guys, better safe then sorry. The hick-up could be the pcm pulling timing due to too much KR.

I quite frankly don't like pre-tuned PCM's, though its a option for those whom are unable or don't have access to a tune/tuner... Idealy a nice tune custom to the car via HP Tuners is the way to go. Street tuning with a wideband then dyno tuning as well and assuring AFR's are safe for the given mods and supply of fuel.

I'm noticing that alot of your sigs have CAI with our pcm's. I really hope that these have been tuned or the cai are not on the cars. The MAF's in these cars are extremely sensitive and the cai's throw the afr by quite a bit. In the last 3-4 cars that we have dyno'd have had cai on them and the afr has been 13.5-14.5 from the start, this is very dangerous. We do NOT recommend running a cai without a custom tune.

Great! I was just about to order Stage 4 and I have the Injen intake and my stock induction is gone. No Stage for me.

I agree that the cai affects tuning VERY much. Every car will be slightly different. I commend Intense for their efforts and quality of parts. However, it is simply not logical to assume that a pre-tuned pcm will work exactly the same on every car. Granted it is easier than tuning and probably cheaper than buying the HPTuners kit, one cannot assume it will give the best performance. A wideband sensor and something to monitor knock retard is of the utmost importance when modifying the fuel curve in any way. I was running a 2.85" pully and 42.5lb/hr injectors with a cai and used a maf-t to tune the car. I used the common C 1 setting recommended by intense and the car seemed to run ok. After installing a wideband I noticed afr's in the low ten's at wot!!! I am not sure if this is what Intense recommends to be a good afr at wot, but I changed my maf-t setting so my afr's are mid to high 11's during wot. I urge all of you who are modding the car to be careful and have the proper monitoring tools to be safe.

well i have the injen cai stage 1 w/2.8 and when i dynoed my afr was high 11's at 6000+ rpm that hiccup you talk about is the engine pulling timing it happened to me with intake and exhaust i put it on a dynon and my afr's were around 13.7 and around 5500 the engine started to pull timing but it was slow a gradual hiccup if you may your problem sounds more serious like the afr's are off so much that the engine instantly pulls timing instead of gradually like it should.

I have the same problem with my Intense Stage 5. My idle is up and down with the car is parked. But the wierd thing about is that my RPM gauge is not dancing with idle. Im getting with Rob this week and hopefully he can figure out whats going on.

i have the stage 3 tune witha K&N CAI and i have 12.1 AFR when i got my car dynoed. I'm thinking about getting a MAF-T so i can at least be able to adjust my AFR but i dont know if it would be worth it cause i am getting the lean code. also i do not have the ability to have a custom tune as of this moment nor do i have the money. i wish i knew how to use hptuners.

I have horrible idle problems still. I have the Weapon R Intake but have the stock airbox still, so it is really just the Weapon R piping and the filter. I switched my gap back to .040 though and that settled it back down a little but still having issues. I'm just going to come up and get a custom tune, its driving me nuts. The Long Trims are way out of wack (-19) and its insane on my gas. Even after getting the Stage 5 flash when I came up there, I have thrown the RICH code numerous times!

When I went to Blanchester to pick up my fiances G6 Converible, on our way back my check engine light stayed on the whole time! I kept clearing it and clearing it and immediately it was back on. To be honest, my car feels slower than when I had the tuning for the current Stage 2 (I think thats what it was).

I wish on your website it would state not recomended with a CAI. I don't have the stock air box. What would you guys recomend me doing?
