Recent Data Log
 

Hoping I can get some second opinions on how my car is running. This is at 18 psi then falling to 16.

Looks good to me.

Re: Recent Data Log
 

Instead of worrying about wot start tunning fuel trims. Looks to mee like the car is lean.

Re: Recent Data Log
 

So the higher the number the leaner it is? AKA the more the ecu has to richen it up?

Re: Recent Data Log
 

But he isn't knocking. I'd go as lean as possible til you knock and back up a little. Running pump gas should limit you to around 11.5 a/f max. Which is a good pump a/f.

Re: Recent Data Log
 

I get a 1 random count of knock once in a while but I've narrowed it down to phantom knock, something with the lifters.

Re: Recent Data Log
 

Yeah it looks good. You could lean it out a little more. If you got a wideband that would really help. I almost learned the hard way!

Re: Recent Data Log
 

I do have a wideband. AEM UEGO. It's between 11 and 10 by redline.

Re: Recent Data Log
 

11 what and 10 what? Sorry I didn't remember seeing a wideband in there.

Re: Recent Data Log
 

11.6:1 and 10.8:1 afr I should say. I didn't have it installed when you were by. I had the kit sitting in my garage.

Re: Recent Data Log
 

I'm guessing 11.6 in the mid-low rpm and 10.8 in the upper range? I guess that seems alright since you're just tuning with the maft correct?

Re: Recent Data Log
 

Yup. I gotta figure out a way to record the wideband though. It has a serial output and a 0-5v output as well. I wonder if theres a way to get that to display on the mmcd program on my palm?

Re: Recent Data Log
 

Not sure.. I haven't heard of anyone doing that with just a palm and mmcd.

Re: Recent Data Log
 

Those timeing numbers scare me. but theres no knock. you definitly need to work on your fuel trims.

Re: Recent Data Log
 

He peaks at 17 degree's of timing wot. What's so bad about that?

Re: Recent Data Log
 

Actually 22 degrees then tapers off at 17. I do need to work on the low trims for sure. I've been trying to get these other little bugs sorted out first before I do 20 pulls on it trying to tune.

But I thank you for the advice, I really do.

Re: Recent Data Log
 

From my experience and searching 1g's tend to run alot of timing stock.

Re: Recent Data Log
 

The stock timing maps are intended for a car running stock low boost though and not leaned out at all. They are usually too aggressive for pump gas and high boost. But every car is different and who knows where his base timing is set at.

Is this car stock injectors? Is that logger really slow? It looks like there are only 2 lines of data for every second.

Re: Recent Data Log
 

He's on evo 560's

Re: Recent Data Log
 

I'm just working with a palm IIIxe with mmcd and a wideband. And yes, 560's. I do not know what my base timing is set at. I don't have a timing light or access to one so I can't check.
