Just finished the turbo kit today and I took it down the road for a test drive and it's breaking up at about 5k rpms..

setup is a turbo b20z on 10psi with dsm 450's and a pherable.net ecu..

Maybe I wired the resistor box wrong or something?

 

whats ur fuel pressure reading at

 

Any boost leaks?

 

1. Check your plug gap & heat range
2. Are you running an msd system or stock ignition ?
Stay away from msd 6als
3. You maybe running too rich or too lean, you really shouldn't be romping on it without a wideband oxygen sensor such as the aem uego 6 in one gauge.

With every ecu we sell/provide we include information on using the proper plugs & getting the car hooked up to a wideband or going to a dyno tuner for tuning.

 

I'm gonna go pick up some ngk bkr7es today, forgot all about that.
I'm using stock ignition
and usually when I do a car and get an ecu from you I plug it in and the car runs just fine, this is a timing issue, I'm almost sure of it now..

 

Yes change the plugs.

 

mine used to do that and once i changed the cap and rotor, all was good again

 

On the to-do list for today..

 

I'll check after I eat my chicken

 

Your playing with fire without monitoring your a/f ratios with a wideband.
You should also sync your base ignition timing to 16.5 deg btdc.
