Kracka, not really. It was hard enough for me to grasp and understand, explaining would just make me look like an idiot. There's more to grinding a cam though than a simple lobe.

 

Sorry if this has been covered or is obvious, but has anyone looked into the cam sensor problem? I saw somewhere that it is related to cars with AEM computers?

Is it actually the sensor failing, or just the ecu losing sync? What's the fix, a new cam sensor? Has anyone looked into building a cam trigger setup? What's the trigger pattern on the cam sensor? Is it a simple 1 per cycle?

 

There is a different crank trigger, it's a 12 tooth. I was asked earlier in the thread if I was running the 12 tooth still, as I had it in the car for quite some time. My answer was "no" I had just removed it. Then I got to thinking, there aren't a ton of guys using the 12 tooth but I don't know of a cam sensor problem from anyone using one.

BTW, Hi Tony.

 

Hi

The reason I ask is because we have similar problems with the Hondas with the EMS and we have a cam trigger kit that replaces the mag sensors in the dist with a hall sensor and solves those problems. The problem is usually that the EMS loses the cam signal at some point and then fires out of time, and you clearly know the results of that. haha

Anyways, if it's worth looking into, we could build something to solve the problem. My guess is it's an AEM problem and not a cam sensor problem.

Or we could put a Motec in it and be done with it.

 

Brad Brooks I believe was behind the 12 tooth trigger wheel for the EVO and it works quite well. There is quite a bit of set up needed to change over in the actual programming. Much of it, as I was going through it, seemed to be wrong on the base settings for the stock trigger. I think if someone smarter than myself or if AEM would acknowledge the problem, it could be fixed just in the base cal. file. The 12 tooth eliminates misfires, long cranking to start the engine and generally just runs better.

I have the new Haltech on my desk, Motec is way out of my budget. I will probably install the new Haltech and give it a shot. Car runs better now than ever but that last cam sensor has me gun shy of it happening again.

 

The Motec is cheaper than the engines the AEM has cost you, just something to think about. haha

Sounds like it's just an AEM issue. The 300z's have all kinds of bull**** problems with the cam sensor and the AEM too, you have to change the trigger disk on the Z sometimes with the AEM. Flip a coin. Nice...

Hopefully the Haltech works out better for you.

 

You are right about the Motec being cheaper than the failed parts! haha

I'm hoping with the complaints I've given and the new AEM being released shortly the issues are going to get looked at. Right now the car is running SO good I'd like to run it again on the AEM, I have to get that 8 second pass out of it. I just don't think I want to risk another problem, so the Haltech seems like a great solution. We will see I guess.

8's on slicks, then 8's on street tires, which ECU is anyone's guess at this point!

 

Im lookin forward to 8's on Pump gas.... Kick *** Dave...

 

Any ECU no matter how good the 'bells & whistles' might appear to be on paper is only as good as the person who's behind the keyboard.

No different to many other systems out there also.

Yeh but VW also got a missing tooth on the crank trigger wheel so it knows when TDC occurs. The cam sensor is only needed for sequential injection on that application.
Most ecu's needs to know where TDC occurs for ignition.
Most modern imports use some type of a missing tooth wheel now. The EVO 10 for example is one of those.

Now where did I hear that before.
You meant your friend was a victim of AmateurEngineManagement. How many 'Another Engine Mishaps did he have!

Mr Autronic be nice now. You know when it comes to AEM you have to be a politician.
You knows it's funny because that term came from the creators. I remeber way back when the 'gold' box was supposedly disguised in their ecu case but that's another story.

I asked about the GEN2's and if they were recoded to solve the syncing issue on certain applications and they said presently it's not!
Anyway I'm done cluttering your thread now.

 

Yes of course... we're talking about Dave in this thread so I'm sure he'll be ok behind the keyboard

Let me ask you, how would the Haltech handle a situation like the fuel pump resistor relay issue on the Evo X's?

By the way.. glad to hear you point out the cam sensor is used for ignition events which I thought as well but didn't know for sure.

 

I agree with Tony 110%. Dave, you should seriously look into what tony has done for the cam sensor setup on the Honda's. It's a very nice setup.



Tony I think if you make it... AEM users will buy it.

 

8's on pump gas.... I'm sorry but, What are you talking about lol

 

i was just thinking the same thing!

 

I like how that honda cam sensor modification works

 

I hear the Series 2 AEM boxes are out for the Evos.
