REDYNOED MY CAR.. Iam pissed
Found a leak in the upper plenum... I fix the leak and bring it back to the dyno
Same TEMPS, Humidity and everything as before.
Same place I pulled 278whp, 253tq two monthes ago...
This time ... 240WHP!!! then I pulled 250WHP for my best that day !!! Iam sick of this BS with the 350z's ECU. I was getting my *** kicked by cars that I should be running equal with and now I know why I was getting pulled..
Iam hoping a UTEC will cure this sht.. Iam placing my order this month

Wow bro that really sucks. Wonder what the ECU is doing?
Honestly I hate these damn ECU's. I'm so sick of the complexity of this crap. NISSAN is a goddamn dissappointment.

SAE corrected both times? Maybe one was SAE and one was standard? or no correction, look into it. How did your A/F compare between your previous dyno and now? Larger tires/rims on the car now? Did you do a 5th gear pull before and only do a 4th this time? My car and many other Z's do much lower in 4th than 5th, on my car as much as 40whp difference on a dynojet. Just today I dyno'd 30whp higher in 5th than in 4th. In 5th the dyno goes slower, more air gets into the cylinders making more power, the "true" power numbers imo(1:1)...

one word-turbo! then all your go fast problems will go away. but alot of check writing will follow suit, lol.

If no corrections then its actual. Meaning you prolly had better conditions this time than last, even if temps were same, barometric pressure can make a difference. Only way to really tell, is open the files in dynojet runviewer, and set em both to SAE correction to account for differences in conditions then see. Does it feel a lot slower?

did you reset the ecu? could it be the knock sensor pulling timing? datalog first with a obd2 reader to see if your timing is being pulled. my car did the opposite. does great on the dyno and then on the street started lagging and pulling timing. endedup being the headgasket blown check first to see if your car is pulling timing and find the reason why before you spend on more mods.

I will post a chart as soon as they send me the dyno graph.. their printer was F'ed up so I told him to just email it to me.. BTW I did reset the ECU two days before b/c it was running like sht and throwing CEL's. A few of the Cels were- Advanced timing error on the ECU, #5 cylinder miss fire code and the code for the 02 sensors. What is an easy way to see if I have a blown head gasket?? It does blow out light white smoke when I first start the car...

I would love for the UTEC to fix your power problem, so you can go on and live in the happy land. But, I have to wonder why you have misfires on the number 5 cylinder. How many miles are on your car? When was the last time you replaced your spark plugs? If you replaced your plugs which ones did you use? What have you changed since the last dyno session?
Thanks,
Jermaine~

You know what when I installed the cams the spark plugs did look completely beat and blown out.... but I only have 15k on the car. Should I really need spark plugs already?? THe only thing changed since the last dyno session is the ECU with the correct fuel map I got back from Technosquare... I also fixed the leak in the upper plenum... but even before I sent out the ECU is was running like a complete dog!
