Interesting Dyno Results

time to delete these graphs!! lol post up your new ones

The graphs are what they are. I still don't completely understand the offset in RPM, but I am sure that Gen has seen my latest graphs. I know he will eventually get his issues figured out and make a great number as well.

IIRC the DI problem OR the coil problem in one way or another caused a lean condition that destroyed the cats. Not FI related at all.

EDIT: I see Mike posted.

Let's hope so... everyone that has looked at the car has struggled to find anything that is causing the low power output. Usually it comes down to "California gas is piss water".

yep, i know it wasn't FI related, but was thinking perhaps OP's car had a similar lean condition at some point resulting in the same cat failure.

A lean condition could do that. Could be a materials defect, FOD, or anything else. With aftermarket tuning I'd suspect a lean condition.

The advantage we have is that most (should be all) forced induction guys are running AFR gauges, and if we see a lean condition we back it down immediately.

Even in the ecutek logs? Everything looks fine in there? hmmm must be something mechanically wrong with the kit? It should be making more power even on CA gas.

LJ from fullblown is reviewing them today,however, on the basemap and revised map that LJ had sent me when I first put the kit on, I made less than 200 horsepower on a dyno dynamics. LJ had reviewed datalogs before then and didn't really make a note of anything terribly disturbing.

When I had the car dyno tuned, my tuner also did not see anything that caused concern. The installer of the kit has reviewed my logs and did not see anything that should cause the power loss. Personally, I just stare at the spreadsheet, stroke my chin, and pretend I know what I'm looking at, so I have no idea what the problem is.

From looking at the logs you posted in whitefrs's thread....

Your only hitting .37 bar boost (5.3 psi) are you still on the stock map sensor? (I assume so since it a 1.5bar sensor)
long term fuel trim of +11%, what afr are you seeing on your wideband?

Just looks like it's not pushing much air.. your only hitting 1.5 g/rev load and 180g/s air flow... if you go by the old 10 crank hp per lb/min .. thats a max of 230 crank hp.

Stock map sensor. I had purchased an omni 4 bar but I was advised not to use it...

AFR at WOT on my wideband is right around 11.5. I'm not sure why airflow would be low--it's the standard Fullblown install so not sure where the restriction would be, unless you think the issue could be the MAF? Any thoughts?

What boost level are you actually running and since EcuTek can't log it, what are you using to tell you what level?

Wastegate has an 8 PSI spring. AEM failsafe reads boost from the manifold.

Those who aren't [running AFR gauges] deserve blown engines.
