I've searched many threads on this forum.
Is there a dyno graph with the air/fuel ratio on the site for any of the CAI's?

 

Bump......

 

I doubt you are going to find it, tvt had one but wasn't able to get a full dyno run in. They are the only ones I know of that had a dyno done with an intake.

Saskins also claimed to do one waaaaaaaayyyyyyyyyyyyyy back in the day, but it looked very fake, then he disappeared. I am not sure if it had a/fr on it though.

 

I've looked at the dyno run TVT did (I can't find it on their website), but I don't remember seeing A/F ratio.
Here's my end point...
We're all getting/have a CAI from one company or another, and we're all getting/have an ECU tune from one company or another.
All the CAI's increase the air (by the same amount to some extent, same hp/tq)
All the ECU tunes are basically the same.
So far only one company has addressed the air/fuel ratio mix saying it's a problem.
The only way for this company to tune your ECU is by sending them your ECU, therefore making your car undriveable - which is not really an option for people with one car!!!

You see what I want the A/F ratio for?

 

We have a data print out of our car with CAI, base tune, and larger injectors. The car was tuned for the larger injectors at the time, the run was basically to see if we overcame the lean issue.

It's an excel file with HP and TQ if interested. The graph we had that day was over time and not RPM, but the data is.

Basically when we had the CAI and ECU tune you would still be able to drive it and it would rev out, but when checking the actual AFR we found them peaking into the 15 and up range.

When we added the larger injectors our AFR went down to about 11.5-12.5 which is way too rich. We put down about 235HP with that AFR. With a tune for teh larger injectors we are in the 13-14 range, which is more where we would like to be on these cars.

 

TVT, you have a PM.
