Timingproblems 5,7 hemi-Msd 6 hemi controller

Post by chargoholic »

Hi guys!

I got a problem, I made a engine swap in my charger 68 http://www.garaget.org/?car=134709
and got rid of the injection to go carb instead and I used the XV motorsports carb kit to do it.

In the kit I got the Msd 6hemi controller to handle the sparks, but it runs rough and weak.
I guess I got an controller thats not been programmed at XV as they said they`ll do.

Now to the problem, I cant change the timing..
I can change the timing in the RPM timing curve file and send it to the Msd but it just dont get it...

I got the min-max timing set to 12-35 degrees cause thats my only way to get the engine to run with somewhat "good" timing.
The map advance curve is stock and this are the rest of the settings.

MAP sensor select- 1-bar
Timing source-built in
Oem timingmod-0 degrees
Idle timingcontroll-ON
Wastesparkoption-OFF

I got full timing(35deg) at 1900rpm
and thats gonna be wrong with the stock timingcurve from MSD..

Thanks for any help!!

Regards Axel

Good luck! I haven't been able to get a response from anyone on any of the boards in regards to the timing on these new hemis or the use of the MSD HEMI-6 control box. I've even sent PM's to certain people who have been working on these engines and gotten no response. It's like the timing info on these engines is a national secret or something! :roll: I suggest you call MSD's tech line about your problems with the controller and see if they can help.
