Default Please comment on my Dynojet result!!!!

05 WRX with Blouch Evo3 16g,650 Deathworks,255 Walbro,Cobb catted dp,inconel up,Turbo XS top mount,IC hoses,stock intake and Scott Siegel AP tune to 21psi 2 years ago.I think thats it.//http://i458.photobucket.com/albums/qq305/SNAKEZ94/03-09wrxdynochart.jpg
I`m not looking for more power as i was told he tuned it this conservative to be streetable and long lasting.I was however concerned about how rich it gets at around 4k.
Any thoughts would be appreciated.
Dave

240whp on a dynojet?!? That must be realll conservative

9.5 to 1 is not excellent, even though it is just for 500 rpms

I would wait for someone that has experience tuning cars to chime in but I am curious about that AFR around 4k as well. Other than that it looks like a nice broad power band. Do you have any frame of reference on this dyno such as stock STI does? It does seem like a heartbreaker if that is indeed 21 psi (barring problems with the tune which could be the case given that AFR, possibly?).

I also just noticed "SAE: 0.98" which I think is atypical.

That's surprisingly low for the turbo and especially so on a Dynojet. Have you logged the car to make sure its not pulling a bunch of timing?

You can probably do it yourself.

FYI, my old 16d WRX made 310whp on a dynodynamics, which typically reads lower than a dynojet. 240 on a dyno jet is about what a stage2 wrx puts down.

That thing is running pig rich though according to that wideband. While it may not be reading correctly, 9.5:1 is almost dangerously rich. Knocking from being too rich is actually more dangerous that from being lean....

Data logging is a good way to check out what your car is doing via the ECU, and you can generally diagnose whats going on

yeah seems pretty damn rich, you will even get some better spool also once thats cleared up. i dont understand why anyone would want that in the tune, maybe something has changed in the last couple years?? hes a reputable tuner no??

you definetely need a protune with the modifications on the car. an OTS map will not work.

you have two maps from scott loaded on the AP. you could reload the low boost map if you have any concerns about how the car is running.

hit me up if you have any questions, be glad to help.

well at 5200 rpm or so, the torque and hp curve dips signifigantly, like your getting timing pulled from a knock or something. and then it goes back up like it fixed itself.

How does IPS tune? With the AccessPort? Opensource? FWIW, I'd look into opensource tuning.

The logs don't look bad at all...but not sure what may have changed since then. Wasn't pulling timing according to what's posted, although timing does seem a bit high @ peak for what the setup/fueling is, but that's more opinion than anything. The MAF isn't maxed out, but FWIW, that log's only showing 19.15psi peak boost, not 21. Then again I don't know what gear it's in...doesn't seem like the most conservative tune I've seen.

The dyno doesn't seem to reflect what's being relayed in the logs at all. I'm not saying there's anything wrong, but to be on the safe side, I'd run a compression test just to make sure the motor is otherwise healthy.

Hey man....little over a year ago i got Scott to tune mine at TopSpeed. Literally the same setup and everything as yours. but i had no cat and i had meth. He tuned mine for 22psi and i got 300whp/300wtq. Spearco tmic, 650 dw inj, blouche evo III, 255 walbro etc. I got him to do a straight pump gas also and i think it was about 280whp at 20psi. He told me it was conservative and my engine should last another 100,000 miles with the tune.

my log was a third gear pull and it was pretty hot. 90+ degrees. boost is conservative and the tune was for 93 oct.

scott road tuned the car on a hot day in atl the summer before as the log i pulled. there were three of us in the car a/c was on, etc.. no dyno tune at that time while he was with SOG. dave's dyno run was the first the car has seen.

Any map that comes preloaded on the accessport that is made to be used in conjunction with an aftermarket turbo should only be used as a 'limp' mode to your tuner or used for a limited amount of time while you're saving up for a tune. Compared to the OTS (Off The Shelf) map there are HUGE potential gains in a customized tune for your vehicle; ESPECIALLY after upgrading the turbo. The tune is the absolute last place you should slack on.
