Hi all
For starters, Im a newb to this. My tuner lives a little over an hour away. And we are trying to figure out a problem when car wants to run af14.7 in part throttle. Right now it just bugs and feels weird. If I go open loop the afr will stay around 13 and every thing is perfectly fine.
I just received an email from Rc engineering about dead times on my rc550cc injectors.
They are:
10v 0.92ms
11v 0.81ms
12v 0.68ms
13v 0.59ms
14v 0.51ms
15v 0.40ms
But when I go into hondata and open my map, I see all kind of weird numbers where the volts are.
They are listed like this:
0v 1.49ms
8.09v 1.49ms
10.11v 0.96ms
12.13v 0.68ms
14.16v 0.49ms
16.08v 0.35ms
24.55v 0.35ms
How do I go about changing the numbers? Do I just change em to what RC told me. Or like where 14.16v is do I change that to 14v and type in the correct time I got from them?
I dont think its gonna change much, but figured I might aswell get the correct numbers now that im about to get a retune anyways. All motor h22 btw
Thanks alot,

Injector dead times 550cc

Change the tables to what they have given you

did it make a difference?

It didnt help with the "bugging" problem. Funny thing is at 5gear / 80km/h theres no problems. My closed loop voltage target is set to 2.0v so it adjusts to ~af14.0. At 2.3v should run 14.7 it will just feel very funny and act up. Like its cutting fuel for a split second and then back to normal, but happens constantly. Slightly push on the pedal and afr goes to 12.5 theres no problems.
Atleast my injector times are set correctly now. I hope its just a tuning issue, but we couldnt quite figure it out.
Another weird thing is, I had it tuned last summer, and ran great. Over the winter I put in 12.5:1 cr pistons. That is the only difference from last year season where I had 11.5:1cr pistons. Also I removed the balance shafts, but I dont think that will make any difference.
I prolly also should mention that when I got the pistons from CP, the spark plugs would slightly hit the top of the pistons due to the piston dome. I got some other NGK iridium plugs which were 2mm shorter and no problems now, heat range 7
