good evening friends

this week I had a problem with my civic. I have a sleeved b16 turbo and the engine detonated. my mechanic says it was failure of the distributor but that night had a new ECU at S300.
what is certain is that the distributor works on other cars.

When The distribuitor fails, the engine can be detonated ?? or is the problem is the ECU map???

I need your help because my engine have only 2000 miles

thanks

There really needs to be more background information before any reasonable opinion could be given. 1) Who socketed the ECU, 2) Age of distibutor 3) was the car completely "tuned" before this went or was it a basemap used? 4) who assembled the engine, 5) what are specs of the engine, and what was used....

This could be ANYTHING either mechinical or software/hardware related.

My guess isnt your distributor but rather the "base map" or whatever was loaded onto your S300. If you were to far advanced on your timing that could have cause this, but like Shodan said ALOT more information is needed.

If you changed ECUs and only made it 10kms, Im guessing that is the problem, especially since you make it sound like it wasn't actually tuned. That what you get for driving on a basemap.

thanks,
so, i give more details:

1) my ECU is a realy hondata S300, not socketed

2) my distribuitor have 13years

3) the engine was assembled and made the running of 1200km at 6000rpm, after this the basemap was placed

4)here in portugal

5)sleeved b16
84mm CP pistons 9.0:1cr
micropolish and balanced crank
eagle rods
polish ITR head
supertech valves springs
Blox B cames
edelbrock victor X
70mm TB
