I have a 97 civic ex that I just finished building an engine for. Its a b18c1 block with pr3 head. B18c1 transmission. I'm using neptune demon in a po6 ecu. 11.5mm wiseco pistons 9:1 w/turbo setup. 900ccFIC injectors.

My question is when I'm making the basemap which ecu type and ecu basemap do I choose. I tried p30 for each setting and entered 900cc injectors and I couldn't start it without increasing te fuel quite a bit. Is that the correct choice?

 

Also if you have to increase fuel say 35% to start the car and get it idling at 14.7 do you increase the whole map 35%?

 

114 views and nobody knows? I have searched for literally hours and find the same info over and over but nothing specific!!

 

Adjust the overall trim if it's very rich or lean, then tune your idle area, and the rest from there.

 

The "Fuel trim" can be used to manipulate the fueling for the whole rom.

A lot of times the when changing the injector size, it makes it about 20-20% leaner than needed. Its completely normal.

Find out how lean... if 30% then put 30 in the overall trim and leave the 2 maps alone.

highlight the whole map and add 30% on both cams is another way to do it... however it will manipulate the duty cycle reading...

 

adjust offsets to get a 14.7 idle, not the fuel map

 

1.) use the P72 basemap
2.) use the ID1000cc battery offsets
3.) SUBTRACT 10-15% from your cranking and post-start values. Don't know why, but this usually solves starting issues.
4.) add 3* ignition advance to your idle range before you start adjusting the fuel trim.
5.) adjusting fuel trim should clean up the rest of it.
