Good morning or evening, wherever you may be.
It has been about 20 years since I have been here - so I come with hat in hand.
Current issue: I bought an 06 Si with lots of receipts. The engine is professionally built and has been dyno tuned via a Hondata Flashpro.
Last night while accelerating, the motor fell on its face and through a CEL.
I was able to drive it home but it did not like anything over a feather throttle and really did not like anything above 3000rpms.
The first thing I did (what I always do) was to clear codes with my Autel. After that, the car would not start.
I assumed that perhaps erasing the codes with the Autel affected the tune so I had to take a crash course in Hondata. (My background is in megasquirt)
I have (think I have) uploaded the previous tune to the ECU but still nothing.
Fuel pump is cycling.
I am looking for some direction.
Thank you in advance.
Tim

 

What codes did you have before you cleared them ?
