Any help from you fellow Autotappers would be greatly appreciated.

IAT's do seems high. Had one reading at 165. Only thing I couldn't figure out was how to check boost. Wasn't sure which column that was.

2nd To 3rd Pull #1

3rd Gear Pull

Accelerate To 3rd

Stoplight To 3rd

Cannot view these....

i'll try to view them when i get home but iat's of 165* are not bad enough to cause the kind of power loss you're experiencing.

Sorry bout that you guys. They are Autotap files.

I will try to post some pics when I can. More of a post for Chrome, VRUS and Rflow to download the files and take a look at.

Jim... What I know is that at 160F the ECU is already pulling timing.. After that it's a downhill slope. On your next datalogging session plot the IAT & ignition timing on a chart in historical view.

I was thinking about it some more after I replied to your email... The I/C circuit must be working otherwise you would have hit 199F and the S/C would have disengaged.

Also, depending on what your A/F was before you swapped the pulley, you may have leaned the car out a bit more with the added boost and that would generate a bit more heat in the motor also.

I think we need to wait until Kleemann gets done reflashing the ECU for you. See where you stand at that point and then re-evaluate.

When I had some sc shut offs,I ran the IAT's and they were between 165-196consistent.Pump was completely dead.

just looking at a few of your recordings so far and i don't think it's a pure pump failure but the runs aren't long enough to tell for sure. that doesn't mean it's not an intermittant failure, but since you're running an aftermarket johnson pump i'm wanting to look in other directions.

your timing, manifold pressure, and iat info looks a LOT like mine did after the reflash where the ecu was messing with those systems. maybe that's simply what i'm looking for and reading too much into this little bit of information???

to be honest, the runs are WAY too brief to come up with any real conclusions. can you make some spirited runs, ie; canyons, on/off ramps, something where you're doing several wot stabs for several seconds at a time and record at least 5-10 minutes worth of data all at once?

Is Autotap the best OBDII onboard datalogger setup, or are there others to consider? I think I'm getting intermittent pump failures, but need to log temps in order to show the dealership.

there are better but i think auto enginuity is the best for that price range.
