i got a b18c1 motor and p72 ecu. the guy i brought it from told me he put a skunk2 base map on. i got high grose polluter readings on hc and high readings on co. new cat installed.

 

timing was at 10 degrees, but when i put it back to 16 degrees the car now puts out more black smoke... most likely running more rich.

 

Is the motor stock? If not what is done to it?

Usually all ecu chips and maps not specifically done for your modifications are over richened stock maps. If your motor is stock, get a stock ecu.

 

it seems stock, the guy i brought it from said he put in itr pison and crank but i think it was all bs. i'll buy a stock ecu and put it in, hopefully it wont be as rich.

 

All you need to do is buy a new chip on eBay. Don't worry, you should be able to blow that motor in no time dude.

 

Yea if its stock, use a stock ecu. There is no advantage to using a modified fuel table on a stock motor, unless it was tuned by someone in person on a dyno. You could probably pick up 5-8 hp by having it dyno tuned.

In your case, use a stock ecu until you can get a real tuneable ecu and buy some dyno time. Best of luck to you.

 

i put a stock ecu in and set the timing to 16 btdc. my hc readings are now around 200 in 15mph and 25mph... everything else is good. any suggestions??? im putting a new o2 on next week to see.
