Same here, the ecu seems so flexible I wouldn't be suprise it would enrich the fuel delivery back closer to stock, it's quite leaner than stock with the injen.

Was yours already reading a bit lower than average like mine and the OP?

maybe its the whole, losing power after the dealer reflash conspiracy

ggpaul · 10-26-2012, 02:31 AM

Hmm I wonder how it would be with this and my Invidia catback (if that shit does anything).

No. I dynoed at 174-176 with just an exhaust.

Yeah so I think your ECU had not pulled torque values so resetting had no help. I'm guess myself and the OP both were down on power so the reset netted power.

If that was the case, I would think the better testing scenario would be to do a baseline run (Stock intake, no ecu reset.), then reset the ECU, do another baseline (stock intake, freshly reset ECU), then install the Injen intake and reset the ECU again for a third and final test (Injen Intake, reset ecu.)

This would rule out the possibility of the gains represented in your dyno being attributable to the ECU reset instead of the intake.

Thanks

TNT please strip off the pics when you reply to a post!!!
That was all 10 pics repeated and wasted time for everyone else reading this thread.

Possibly would work. I would almost bet that just reseting the ECU before the baseline would be enough unless they are all done on different days then yes reset everytime. If you have a tune though, no need as I think they manipulate the torque modifiers to prevent ECU "hold back" on power.

Ahh, this must be why my dynos only yielded a 1-2whp difference.

Guys take a look at that torque curve on the stock run. It is falling off way too soon and way too harshly. Looks like there is some sort of restriction or the ECU has learned to run that conservative.

I made this same comment about this dyno in another thread. He's at least 20 ft lbs weaker at redline than a typical 86.

jadewbj · 02-14-2013, 10:54 AM

That is a really low baseline. Lowest I have seen.

LeeMaster · 02-14-2013, 11:24 PM

it looked like they lifted off the throttle or werent giving it 100% towards the end yes no?
