So to make a long story short I moved from Seattle to Las Vegas. I had my car shipped and the company did 12k worth of damange and paid to have it fixed. One of the things replaced was the PCM or ECM. Now I got my data logger cable and am able to read my stock map. I have a few issues.

1. Is it normal for the EvoScan or ECUFlash to cause the ACD / ABS lights to blink while connected? If it is, would this be safe to do a log on? If it is not normal anyone have any steps for me to try. I got the full bundle for limitless's website.

2. I had been tuned / flash for what i would call mid performance (20psi max) I got the car back and the only thing I changed was I upgraded my stock MR blow off valve to a GFB Stealth FX and only venting a little bit of air (maybe 10%).

3. I'm hitting fuel cut / getting the P0234 overboost code. I turned down my manual boost controller because I was hitting the fuel cut right in the 4.5k to 5.5k range and would imedeatly throw a SES light.

If someone can help me fix the above issues that would be really helpful as I don't know anyone here in Vegas but need to resolve this ASAP.

Kind Regards,
Loren

 

Oh I turned down my MBC and I'm only maxing 15.5 to 16PSI all the way up to around 6k. forgot to add that.

 

Assuming that you are going to tune this yourself, go to the boost limit under the turbo heading. What you will see is probably is something like this:

255
255
255
255
250
245
240
235
235

Each corresponds to an RPM point and references a load % in your tuning maps. Up these about 20 across the board and your fuel cut will/should be fixed. The blinking light thing I havent ever seen before but if the car still operates and isnt flashing when unhooked I wouldnt be overly concerned.

The best course of action would to be retuned by a local. Doug's Dyno is local to you and he knows his stuff, uses a Mustang, and is someone I can vouch for.

275
