BTW - dd you EVER ht the REV LIMITER while on the dyno - another AEM issue is the violent base line rev limiter setting - it created such a violent back fire that it basically expoloded the wall of my exhaust port like a bomb. It is a real pain in the *** to remove and replace the entire head for sure ! I think it needs more of a soft rev limiter than a sudden switch that sends raw fuel into the manifold to explode like the way they have it set.

As for the AEM approach to R & D - its a bit odd that a large company like that would release something with a serious flaw like the mis fire issue

I heard their supra board has similar issues which were never resolved and that most of those guys use a seperate ignition system

Its also odd that they have posted nothng about it on their official web forum ???

I take it from what you are saying the new unt they claim was sent to Frank on Friday is not fixing the problem ???

 

If its misfiring - you get raw gas dumping into the manifold and exploding like a bomb and shooting flames out the back like a giant fireball

When my car hit the rev limiter with me standing 50 feet behind it the fireball was very intense and the sound was loud like a shotgun blast

I don't know if the misfire caused your turbo to blow up - but I am sure that having the spark go out and dump raw fuel into a glowing hot manifold is not the most stress free operation

I know the rev limter was enough to blast a hole through the exhuast port into the water jacket - thats a lot of force

 

For me - the thing that makes the AEM problems so irritating is that the unit is so good in other respects I know its something I want to use - so its like I need to get this ignition issue fixed

The thing that makes it hard is navigating the morass of voice mails and etc at AEM to reach the right person to discuss this issue - that and the fact that they freqently say they will call you back by the end of the day and don't

 

not sure if it works yet...got on the dyno and the turbo went...yeah they dont care they keep sellign them. ( i heard like 50 units not sure how accurate that is)..meanwhile they knew all along because of mine and another car at SFP havent been running right and havent been able to be tuned to their potential..**** if I wanted just 400whp I would have had you dynoflash it and been happy...and not have all these problems..I consider their approach at R&D very odd....**** like i said before i would have liked to know if my car was a mule before i decided to put that in...I will let everyone know exactly what happens...Im gonna call them monday and go over every aspect of this...with my turbo going....im just not gonna be nice anymore...ill start a new thread so its archived as well...and we can all keep it nice and clean so it will be on here for all eternity..lets see how aem handles this...just be careful al..dont push it and god forbid blow your motor

 

well last time we waited for them to call back and the guy even gave frank his cell number and sure as ****...voicemail...u would think they would call the jackasses who were your mule....I heard RMR had their car at AEM doing R&D for them..Ill bet my *** RMR didnt pay for Tuning or the AEM system....why should I? when now im siting with a turbo thats fried and extremely suspect

 

Nice #'s Al.

Sorry about your trouble Pesto. But, thanks for sharing the info with us. It just might save others from the same brain damage and frustration, not to mention $$. And you do have a point Pesto, word of mouth can make you or break you, especially if it's a BIG one .

In light of your experience and Al's testimony, I for one will not be going with the AEM. If for no other reason, it sounds like their customer service is .

Good luck guys, keep us posted.

 

The AEM sounds like a real problem. There are some big vendors here that sell the AEM and recommend it. It'd be good to hear from them on their experiences as well.

BTW Al, is that low boost/pump gas dyno plot above through your new converter?

 

Yes - that is with my new converter - 3" high flow UR cat

 

So what does it run with YOUR DYNOFLASH ?

 

RUN - whp wise or 1/4 mile time wise ?? Here is the dyno sheet from a pull I did at a dyno day back in November - one pass with the dyno flash - just wanted to give a demonstration that you can make good who with a reflash

Time wise the car ran a 11.62 with just the reflash

 

Actually, I meant what kind of HP does your car put down at 20 psi and street gas using your dynoflash?

 

I am happy there is harmony between Al and MP5 and Pesto.

Sorry to hear about your turbo, John - not good.

 

I was looking at the AEM but used to have a Motec on a TT Rx-7 once you go with something like that there is NO support, **** the Motec was great when it ran right and after 6 months of NEVER running 100% I sold the car and everything and bought a NSX. The AEM is a piece of **** and was trying to get it to work on the NSX's as well. It's smoke in mirrors and there support sucks ***. I did the Vishnu piggy back so I did not have to screw around with it this time, just start it and go. Looks like you guys were like me with the RX-7, 1st on the block and never got it running right, I used to get pissed just looking at the thing lolrof. I wish you luck but AEM support sucks ***, Motec is about the same because they are supporting million $ race cars and you don't mean **** to them, PI 30k and above are great but not going to pay the price of a evo so a EMS. lol

 

Dynoking please share your experince on this link...Im trying to gather knowledgeable people who had good and bad experiences with all systems to figure out a solution so no one else has to suffer at the hands of these greedy bastards again

Can you beleve that back in the day when had a NSX I kept it bone stock! Ran perfectly but slow and went through tires like crazy - I put on about 50 k miles and went through at least 10 sets of rear tires and 4 clutches. Dont try driving a nsx in the snow ! Mission impossible !
