Please scan and post. Just read the manual as logging is super easy and do a second gear pull to rev limit in 2nd gear two or three times and post your timing curve. Don't sweat the little stuff as I had to learn how to do it also and it was surprising easy. Hint....a cave man can do it.
Here why.........
1. My car lost midrange power after tuned at Cobbs in Plano
2. Later dyno pulls at RPM to verify Cobbs output and AFR to see if the car would learn and if it would change on it's own. Cobbs post tune dyno curve and RPMs dyno had pretty much the same curve and AFR.
4. As posted above....found out the hard way the timing tables don't work.
5. Been busting my balls to make sure it wasn't intake temps, water temps, oil temps, or lean under 4000 rpm. Added a new oil cooler, did some air cooling tricks so the Gen 3 intake wasn't an issue and pulled out some fuel below 4000. My current intake temps vs ambient are less than 8 degrees difference plus as your aware, (I'm in Dallas) the air temps are very good right now. Low 70's.
Logging today.......Whether it be the new oil cooler, me tweaking the intake temps or just weather....... The car is not pulling out timing throughout the range, it still is however pulling 3-4 degrees between 4500-6000.
Checked the curve of my baseline pulls and my assumption is that before the Cobb tune, it wasn't pulling out timing because the shape had changed. (No dip before)
In the process of e-mailing Calvin my run logs of today. But that is two in a row with more than likely the same issue. Humm......This just might be an issue.
