Me too, 3rd or 4th gear, up above 6000rpm (PnP Platinum Pro).

 

I was thinking about switching to Haltech if I had any problems with my repaired AEM, and so discussed it with RevZone (link). They told me they have installed a few Haltechs on S2000s and had to work through a few issues with the unit with Haltech. It might be worth contacting them with your problem and seeing if they had a similar problem and have a fix.

 

Did they say they managed to resolve the issues? I'll give them a call tomorrow

 

Who is ur tuner man? You from Sydney aswell?

 

My Tuner is Steve at MSC in melbourne. He is a very reputable tuner and knows what he's doing. It's 100% the haltech and not the tune. I still haven't had time to speak to rev zone yet though

 

I was out on track last night and was consistently suffering misfires 4 or 5 times per lap. I always thought this was just my tune, but now (given this thread) I think it may be the ECU. I have opened a dialog with Haltech to try and get to the bottom of the problem. Whilst they have told me "There is currently no known fault with the Pro AP1 ECU" they are willing to look into it if we send them some logs. They have specifically asked for logs with all the "Old Home Counts", so I will be doing some logging over the next couple of weeks. If any of you could also provide your logs (to me) I will send them on to Haltech also. Hopefully, if there is a group of us, we can get this resolved.

 

Subscribed - I have one ready to install now. I went this route this round as I did not want to mess with AEM's issues

If anyone finds a solution I am insterested as I can send the box back before it is installed and hopefully get the unit repaired.

 

I spoke to a tuner today who claims he can fix the problem by updating the "firmware" on the computer. Has anybody tried this?

 

This is honestly the first time I have seen others saying the same things as me, but then again, I don't see s2000's on a daily basis running this ECU.

Also have subscribed in hopes of finding a fix

 

Can you find out what firmware version he suggests will fix the problem?
