Finally a log for my car!

[re-rx7]

This was for a 2nd through third gear pull. ALot of you were asking for one and this one is for my final as close to no knock tune.

That really doesn't show much except your coolant temps are causing you to pull 1° of timing, your IAT's are very high, and something's up with your TPS as you didn't hit 100% until almost 5000 RPM's (unless that was part of the 2nd gear pull).

120 ait damm

I can email anybody the ful page just cant get it to post. 120 is a high IAT? Coolant temps are acutually 200 flat scaled. So thats about right. Didnt have much room 2nd gear started at around 5000 rpm's. What are good IAt's?

 

[snowborder714]

IAT's should be as low as possible, but usually as close to ambient as possible is what you'll see. They might get 10-15° above, but it all depends on the car.

 

[re-rx7]

Ok. you have an email i can send you the whole log.

Just sent it out to you. On anothe rnote could those high Iat's cause this low timing issue.?

 

[snowborder714]

Attached the log for everyone to view.

 

[re-rx7]

Thank you. Any opinions?

Doesn't look horrible except for the coolant temp and IAT's.

There's no wideband logged, but the target AFR's seem to be around 10.2:1, which is fine.

WB shows 10.9-11.0 thru the whole run. Would a fmic help things? Im on a Hahn big smic with a T28 pushing 19 psi. The coolant temp arent you supposed to read the scaled version which reads 203. Is that still warm? Secondly is the IAT before or after the turbo?

If the wideband show around 11:1 then you have some airflow configuration to do.

I'm not familiar with EvoScan, so I'm not sure what's to be read.

YEs it reads right around the 11.0 mark. Airflow configuration? PArdon me, but i have someone do the tuning for me. At this pt im almost tempted to do it myself. Overall do you think this was a goodjob?

 

[snowborder714]

If I'm reading it right, then yes, the airflow still needs some work (11:1 of wideband vs. 10.2:1 of estimated AFR).

Other than that, it looks fine.

Then, stay with me here, how can i get this thing to like timing? I know the Iat sensor is in the maf. So maybe some heat management? I have all the shields on minus the 02 housing. Thanks for your help.

 

[snowborder714]

The 2g will naturally not like timing as much, but I would work on getting IAT's down as far as possible.

 

[re-rx7]

Thanks man. thats what i was leaning towards.
