Can someone tell me what afr I should be aiming for when starting engine from cold? Wideband read 10.5 on initial start and rising to 12.1afr. Struggled to stay running on initial start up I imagine its to rich?

whats up dude? have you made any progress? Sorry dude hadn't given any update. Didnt get a chance to check fuel pressure yet been up to my eyes with work. Hopefully this weekend ill get something done. Need to set valve clearances and fit air intake kit. Car is running pretty good as is and pulls r...

it doesn't necessarily have to hunt or hesitate to have a vac leak, you might have a vac hose that isnt pushed on all the way, or one has a hole in it,and low compression can act like a lean condition. is the motor fresh? how old is it and what is the mileage? what kind of Honda is it in? here is t...

one other thing i thought about, if you had to add 33% for it to idle around 14.5 and then had to take fuel away on the rest of the map, did you check for vacuum leaks? that makes the most since to me now that i think about it, sometimes its the simple shit that we overlook, i know from experience....

OK, i dunno, when i opened your cal. it had closed loop enabled. maybe a bad software install. have you done a fuel pressure test? clogged fuel filter? i am just trying to give you some ideas, but a stock engine with stock injectors, and a couple of bolt ons you shouldnt have to add 33% for fuel tr...

Fuel pump and FPR are stock oem. Here is a screen shot when I open the calibration I posted on here. It has closed loop disabled.

one thing that i notice is the you still have closed loop enabled, you cant tune like that dude. that is what is throwing you off, you are trying to tune in idle first with closed loop and it is throwing you off everywhere else. even though you are adding overall fuel to the mix, closed loop is tak...

Your call have an problem This is an full stock OEM P30 created on eCtune thanks for reply. What is the problem with my cal? The cal. your seeing is part tuned by me. I have pulled lots of fuel from the map due to been very rich throughout the map after doing injector calibration to reach 14.7afr i...

what do you mean by breathing mods? intake? headers? exhaust mods? what all have you done? keep in mind that a engine is a big air pump, so anything that you do to increase the airflow, you also have to increase fuel. or you might have set something up wrong, why did you use the edm map? try the jd...

Hi, Has anyone else noticed the P30 EDM basemap runs really lean? I selected standard injectors, P28 ecu and P30 EDM basemap and on start up I had 18.1 afr on idle, it was the same throughout the map, really lean and had to add lots of fuell. Car has a standard b16a engine with just breathing mods.

Are ectune basemap ignition values same as a stock honda ecu? i.e P30 ectune basemap vrs P30 honda ecu. I understand that the fuelling tables on ectune basemaps are rich for safety but how about the ignition tables and is it possible at all to alter ign timing doing a street tune? Thanks for any hel...
