I'm not sure what you mean here.. Me along with many others have no issues at high loads...
I've made over 1700hp and there's guys making over 2000hp with autronic.
I've made close to 1000hp on a 4g63 with cdi and no issues...
I've made 700hp on stock evo ignition.

More then likely those lot of guys you speak of had other issues...

BTW: most rally cars run autronic/motec ecus.

 

Just so you guys know even with a 60-2 wheel the ecu still doesn't have enough infomation to know how to fire sequential ignition. It can fire in wastespark but can't fire direct unless it has a cam sensor to tell it when tdc #1 occurs..

Even the Almighty gold box can't do it.. LOL...
BTW: Hi Tony..

However there are some ecu's that have the capability to know exact crank position at all times and would be able to do it but are way out of reach for most of us...

 

Yeah, I'm aware of the success the Autronic has had. I just distinctively remember that when the Honda PnP board came out, several big name honda guys had problems with it either dropping spark or randomly advancing spark above like 25 PSI.

I never had an issue with the SMC I tuned. I loved it because it was stupid simple yet very capable of running a motor very well. I'd love to give an SM4 based ECU a shot, but I'm broke and the stock EVO ECU is pretty damn good so I don't see it happening any time soon.

 

wow logged in after a loong time 1st i c bad bish broke.. well good to c its fixed again...

aw i used a Haltech on my evo 3 after coming home... it was good but not enough.. selling the car now coz got a evo 7 last week.. im thinking of haltech platinum 2000.. i know the platinum 1000 would do the job for evos 1-8... dunno which one dave gonna use...

it has a function called Knock threshold so im think it has the knock controle ( dryad001 )

 

This is what I was getting at. If it's a trigger pattern issue, why does replacing the cam sensor solve the issues? Is it or is it not an actual sensor issue?

 

tony, it is an sensor issue BUT the sensor still functions. Changing it will make the misfire go away, so it has to be atleast sensor related.

For an update, AEM has been in contact with me over the last few weeks because of the new units/software coming out. I had given them a long list of complaints quite some time ago, never heard anything back but hoped they would be fixed in the new boxes/software. Well I gave them the new that I was switching to Haltech and now there is a fairy major effort being put forward to figure out what the problem is, why the car sync's slow (which is probably the problem to begin with) and they are looking into getting to the bottom of it all.

I hope they do, I'm very comfortable with the AEM EMS after tuning so many.

 

From what i understand is the AEM requires 720 degrees of crank rotation to fire is why its slow starting.. the Haltech is immediate... My guess is everything they say they will fix they wont.. I also guarantee the hardware is nothing close to the Haltech Hardware.. Its been for years that haltech has had the hardware end covered just the software wasnt always user friendly.. Now it is though...

As far as I've heard, AEM is not advertising any new hardware in their series II boxes. A better injector driver circuit and such would have been welcome. It appears to me that all you're getting is password protection, larger internal logger memory, and a few other minor features. I do like the AEMtuner software as it kind of looks like the Haltech but it's still in beta form.

Once again, AEM has software out and will be relying on its end users to work out the bugs for them.

I am currently looking at replacing my AEM in my EVO with a Haltech.

 

Maybe just bad luck on my end, but my last experience with Haltech was with an E8. The first 2 units we tried were dead, right out of the box. Third time's a charm. That was enough for me.

 

Too bad it takes someone of Davids caliber and rep to get them to wake up and realize that the unit does have these flaws. When others have pointed them out as well. Regardless I am thankful that they are still being pushed and might be getting addressed. In the end it could be a win for AEM electronics as a whole.

 

How would the Haltech handle a situation like the fuel pump resistor relay failure for the Evo X?

 

Where are the Haltech proponents in this thread? I thought this would be a good practical example to discuss. Any takers?

 

Dyno'd the car yesterday with the AEM on it, 710 whp at 40.09 psi, biggest number ever on the small cams. I was not happy with how the car was "acting" so I took it back off the dyno and we put the Haltech on it. I have about 5-6 hours in the base map so far, learning how to move around the software, transfering data from AEM to Haltech etc. Plan to put it back on the dyno with the Haltech today or tomorrow.

Big thanks to Crispeed and Mike at AWDMotorsports for sending the Haltech and setting it up. The car fired instantly and ran, no problems. The time I have put in it now are changing sensor calibrations/injectors/rev limits/fuel and timing tables etc.

 

I dont understand why you REFUSE to just start a new thread.. We dont need ongoing discussion about Haltech for a X in Davids thread.. START A NEW THREAD and ill be glad to go in and discuss whatever you like along with crispeed..
