I am currently in contact with the Better Business Bureau regarding the ATI Procharger's design flaws.....ATI has replied to my complaint.......they are claiming, once again, that they haven't had any problems with this kit.......and are trying to imply that i am the only person that has ever experienced problems with their kit........they are assuming that i've made modifications to my car, and to my kit, although i'm totally stock..........this is our chance to get their design flaws exposed to the public........please PM me with your serial number if you have experienced problems with your Procharger, as i am preparing my response to the ridiculous letter that they sent to the BBB

 

I have Dos Cojones; serial # sent.

Godspeed in your stock 6mt bud, you worked hard for that 5.8k

 

I will PM you with my Serial #. I have to admit I haven't been able to talk to ATI but seeing that I tried and even after leaving a message they never returned my calls, can say their service is not up to my standards. Grubbs Infiniti who installed my procharger has fixed all the problems caused by ATI's poor design. I know in my case the frame had to be shaved for the procharger not to put so much pressure on the blowers down tube that it would pop off or rattle continuously.

I like you, believe that the procharger was rushed to the market to get all the earlier money without the proper R&D. They are now expecting the customer to do it, even though it was sold as a finished complete kit that anyone with a set of wrenches could bolt on without any problems. That of coarse is a big NOT as we now know.

I can only hope the BBB lets them know that this kind of practice is not what the BBB expects.

 

I think the BBB is going to very interested in the stuff that ATI has been doing........check out the letter that ATI sent them.......apparently ATI tells the public one thing, and us something entirely different......the letter and the "technical notice" they posted here don't really match up......here's the link to the letter:

Letter from ATI to the BBB about me and their Procharger

I couldn't get the letter to post here for some reason.......but it posted there pretty easily........notice that it's dated 11/26/03, and written by their Sales Director........also take notice that he has no idea what the differences are between the "complete kit" and the "tuner kit".......for some reason, he thinks the "tuner kit" comes with a variable boost option......last time i checked, both kits were 7psi.......and this is one of their top guys writing this stuff!

 

EJ-
You did not blow your engine, right? IIRC, you are having problems with detonation in the upper rpms? What are the a/f ratios when its detonating? What did ATI say about, assuming you talked to them directly about this?

Like I said in another thread, I do think that is messed up that they claim your car has other mods when it does not.

 

Can someone post the letter here.

Thanks,

BlownG

That's right, my engine still lives, at least as far as i can tell......i had a compression test done, but not a leak-down......which would tell for sure

My A/F at 6488rpms was 11.8:1 on my last dyno......when the crackling could be heard......my tuner backed off from there to keep from causing serious damage

ATI asked me about all of the other variables........gas.....plugs.....wiring.....hoses.....MAF. ....and fuel pressure......obviously if i'm getting an 11.8:1 all of those things are working fine.......6500rpms is where the stock timing really ramps up, and thats where it starts causing problems on my car too

 

EJ are you looking into getting the J & S Safeguard device?

 

It does sound like it could be a timing issue...but I have more questions. What were the ambient conditions when your car was being tuned? What plugs were you using? Have you had any trouble prior to the ATI with your ecu throwing codes, especially anything to do with the oxygen sensors?

Sorry for playing 20 questions, but I would truly like to learn more about your situation....

 

Possibly.......i like it........either that, or a reflash........it all depends on what happens in the near future

No problem, Gary........i already went through this with ATI.......it was hot outside during my tuning, inside the shop a big fan was put in front of the intercooler..........i have the NGK LFR6A-11 coppers.........the only code my car ever threw was when Nissan was replacing my tranny.....the movement of the engine had caused an intake hose to come loose......i recieved the most recent ECM flash, and new MAF before they figured out it was an intake leak......but the codes thrown were intake symptom codes

 

Did you guys try adding more fuel, even though the a/f ratios were reading in an acceptable range? I do believe that the timing maps are a culprit here, but I'm curious about the wideband that was being used. Are you sure it was really getting enough fuel?

 

that sounds like the problem. I told a guy I know about Z's and blowers and he says he would bet the cars isnt getting enough fuel.

 

The wideband is good......they tune lots of imports there........the tuner has been working on import race cars for about 15 years.......yeah we tried adding more fuel.......the first time i went in my last slider was a little above the middle of it's range.......after my second tuning he put my slider all the way to the top, since giving the fuel pump 100% signal was all that could be really done at that time.......it didn't help

 

Widebads are great, but you can't cure an octane problem with a "perfect" air fuel ratio. You've got to take some timing out of it.

 

Precisely......if the fuel pump's already pushing 100%.......either i have to change the timing, or i get water injection.......but the FMU can't help anymore

 

One way to rule out (or confirm) timing and/or low octane would be to run a can of NOS "race booster" (really adds a little less than 2 points). All others from the auto store are crap. This should be enough to make up for a few extra degrees the ECU may be kicking in at high RPM. If that works , then backing out a few degrees via J&S with 100% 91 pump gas should work. Just a means to try before you buy.
