Does anyone know if its normal for the rpm's to go from 750- 1750 and back and fourth right after the cars started till i get it moving and if so will it stop after i get my pcm case learned on tuesday, im not planning on driving it anywhere till then.

 

Bump

 

Anyone

 

Yes,

You're PCM is remapping everything, or so I've been told from Intense. Give it a few days to work itself out.

I'm having major issues with my stage 5, rpm issues, and the air intake. That's because, and this may help you out, if you have a cai. The PCM from intense is setup for the stock intake, so you may have to get someone from intense to help you fix it. I'm driving to their shop in June to have it adjusted.

 

thanks, i had a cai intake and it was injen but i couldnt stand the ugly dent so i put stock back on when i did the kit but left the bottom cover off

 

That would make me think there is trouble with the MAF signal.

Do you have a MAF-T? or the Custom PCM?

The PCM doesn't remap itself, other than fuel trims tables, and 1000 rpm varience is a pretty big "remap".
If you can I would scan the MAF freq values, 1800 to 2500 is normal for idle start high and works it way down as the car warms up.

 

custom pcm

 

Do you have an aftermarket intake? That can mess with the MAF, otherwise I dunno, haven't seem what intense does with their tune.

 

i put my stock intake back on but the MAF is only on with one screw cause i lot one and didnt feel like finding something to replace because i had been working on the car for 4 hours already. I dont have any codes right now other than the case relearn not done yet code

 

is this tuning issue with an aftermarket intake just with the intense kits or is there an issue with this regarding hp tuners aswell?

 

^^^^
I would think that would deped if you used the hp tuner and tuned it for a car with a intake, intense uses hp tuners but they tune for cobalts with tstock intakes

 

well what do you do if you have an aftermarket intake?

 

I figured I'd rather have my PCM tuned to my car. I'm goin to buy the stage 5 separatly and get it tuned by a guy I trust that's by me. How do you like your stage 5 so far?

 

To be honest, without the correct tune, I cant give you an honest answer. I'm kinda disapointed that Intense would send out a PCM for people and not asking if they had a CAI. I took it to the Dyno the day after, and a ran a very unimpressive 231hp, and I have a crapload of mods to my car. The car stutters when it runs, like it's trying to do something, but the PCM is retarding it to do otherwise.

I'm bringing the car to Intense in the middle of June for testing and dynoing, so we'll see how it goes.

 

So after i get the case learn done all my problems should be gone right?

 

Does anyone know if Intense will start or has started to sell there PCM's to run with a CAI. I know that they have it programmed to the stock intake.

 

hondaeater, what kind of boost levels are you seeing? I have intense stage 4 along with an aem cai and am seeing close to 18 lbs. at 7000 rpm. I am a little worried now after seeing this thread that my car may not be making the power it should. I have not had my car dynoed yet, but I think I am going to soon to see if the car is running as hard as it should be.

 

Yah im getting the stage 3 kit and im getting it dynoed at the end of june so we'll find out if it is putting out what it should be.

 

Anybody have any ideas or if Intense can answer this!

 

This is bull, this crap shouldnt be happening on an aftermarket tune, and aftermarket tune is to fix all the problems that a stock PCM cant read. WTF!!!!!!!!!!!

 

So you have the intense stage 5 and you only dynoed 231HP?

 

Will all my problems be fixed once i get the case relearn done?

 

you must think that they are creating the pcm tunes to work with their kits that they put togeather. and like all business it will probly be more money to get the tune for the cai. (just me using my head but it may be the same price.)

 

Just like the stock LSJ PCM and the GM Stage Kit PCM, we write our PCM code for the stock airbox. Anyone who changes airboxes with our PCM can expect the exact same results they would get if they were still running stock or GM Stage PCM's with an aftermarket airbox.

For example, if a certain aftermarket CAI kit makes you run 2% leaner at point X and 4% richer at point Y in the RPM range with a stock or GM Stage Kit PCM, you can expect for that same aftermarket CAI kit to effect the same changes with an INTENSE PCM tune.

Since the factory MAF sensor is incredibly sensitive, the only way around this is to do a custom dyno tune with each brand of CAI kit on each of the five different LSJ-powered vehicles. We've already done MANY hours of LSJ dyno tuning, but there's just no way we could possibly afford to dyno every possible parts combination.

If you have a Stage 4/5 kit, and you're only seeing 231 WHP, then it's likely you have something wrong. In a case like this, we would recommend the following:

1. Verify you're running the highest possible octane/quality fuel. 94 is best, 93 is good, and 91 or 92 is OK. Poor fuel will result in KR, which will result in lower horsepower numbers.

2. Verify your plugs are gapped correctly. Having the gap above .035" will result in spark blowout at the higher RPM ranges with the smallest supercharger pulleys. Spark blowout will result in a normal looking dyno chart at lower engine speeds, with a significant power dropoff at higher engine speeds.

3. Verify you don't have belt slippage. Make sure your boost numbers correspond with the dyno charts and information we show on our website. Belt slippage will cause lower boost, and this will result in lower horsepower numbers.

4. Make sure you have the right parts from a specific package. I just got an email this morning from a customer who purchased a Stage 3 PCM a couple weeks ago, which was programmed for 42.5 pound fuel injectors. Then he later purchased 60 pound injectors, which are 41% larger. He didn't realize he needed to have his PCM reprogrammed for the larger injectors, so he is just flooding the cylinders with fuel now.

5. Scan the car, or have someone scan it for you. When you're modifying these cars, there's just no substitute for the sort of data you can get from a WOT scan. Armed with this information, we can help solve just about any sort of problem.

6. If all else fails, a dyno tune will normally help resolve any and all remaining issues. When you can scan all sorts of PCM parameters and see horsepower, torque, boost and wideband air/fuel ratio all overlaid, the tuning value is very high.

Also, please feel free to email any of us at any time. We're always eager to help our customers and friends get the most out of their combinations.

 

Sounds like a vacuum leak to me. Did you check for leaks around the injectors?? They VERY easy to mess up on the install since you have not only the injector o-rings, you also have the plastic inj cup's o-rings that can fail.
