WOW! Why is it that i have just now heard this about the AEM?! Maybe i don't read enough on the forums?? A year ago the AEM was the best thing u could get for the $ and i had NEVER heard of this problem or i would have never went AEM I run the AEM on my daily driver EVO that is making 700+whp on E85.... This has got me spooked now! I cant have my AMS block being blown to bits if my cam sensor goes bad...

Is there anyway to fix this issue without switching the EMS or throwing back on my stock ECU and going SD? Will the 12 tooth crank sensor fix it or is it in the AEM software and will freak out no matter what crank gear u have?

Well said Al. Once the pain and disgust clears you pick up the pieces and go stronger. Davids honesty and integrity are bar none!

I have seen two Evo's that have had bad cam sensors with stock ECU's. I don't feel that the AEM is the cause of the sensor failures. We have had a cam sensor fail on the orange car one time. It would spike 12k+ RPM out of nowhere. Thankfully we did not lose a motor due to the cam sensor issue. We replaced that sensor with another used on and have been on that same sensor for the last year without issues. Every standalone (except maybe Motec ) is going to have issues at some point. If they did not then companies would not keep making new and improved versions. When it comes down to it, put whatever standalone you feel comfortable with on your car. Just remember, that standalone is only as good as the person behind the keyboard.

I have let ours out at 50psi. She comes out tires a blazing!

Turbotrix I agree the stand alone is only as good as the guy pushing the keys I am pretty familiar with AEM as i use it on a daily basis and would hate to switch over as i do really like its ease of use... and well im just plain familiar with it and my car runs like bat out of hell! But my question to you is will the same RPM spikes happen and cause damage when the cam sensor fails using the stock ecu and other stand alone units on the EVO? Or is this only a AEM thing? I would think it would do it on stock ecu as well but ive never had it happen 1st hand with logs to show...

I do know one thing i am going to buy a new sensor ASAP.. as in looking for best prices right now lol as mine is on the original one and about to hit 70K.. 2003 model

PS. Wheres the cheapest place to get a NEW OEM cam sensor guys?

The two stock ECU cars that we saw it happen to were only basic bolt on car. We don't have any data logs on those cars. They were randomly misfiring/stumbling. Cam sensors were replaced on both and they were good as new.

i may need one too.. a quick google came up with this...but any other suggestions would be great.

So it comes down to which is the lesser of two evils then.

Options:
A. Run AEM and pray your cam sensor doesn't take a crap
B. Run haltech and pray you don't get bad gas

2high I was thinking the samething here

Damn Dave I feel REALLY bad for you buddy I know you are a devoted man when it comes to the the BadBish. Just hang in there, things can only get worse Thats what I always tell myself anyways, when I have sh*tty days.

So are you saying that if u run a haltech that when ur cam sensor goes bad it has some kind of safety mode and there is noway possible of this happening??

I'm not done, don't take me wrong. I just don't know if I have enough time left this season to take it all apart, fix it and get it to the track.

The car was running better than it ever has, I should have been video taping it because the difference really is obvious on how the car actually runs, accelerates etc., hard to describe.

Tomorrow morning I'll get with Daniel and see if he can get the entire engine yanked out or if he's just too backed up, as has been the case. I got lucky last time and apparently nothing was hurt other than the head, I hate to try my luck again. Normally something like this atleast hurts the ring seal.

dam sorry that happen i hope you get it together and run the car

Damn David I am sorry to hear about this. As Jeff said it could always be worse. I know you'll keep at it and as always you have a extra hand to turn a wrench just a phone call away!

I want to see her in the 8's this year. I don't care if I have to rent D42 in November to make it happen ha.

Bro - your bro one time R & R my engine out of my race Evo and it was sitting and idling by 1:30 p.m. in the afternoon. If anyho0ne can get that beast back together before the track closes its you guys!!!!!!!!!!!!

I just got a mailing from Norwalk saying that they have a big event at the end of October - get moving man - the entire Buschur fan club is counti8ng on you !
