more questions about utec...

Anyone else have any imput ?

Last night i backed it down 10 around that area, and it took the problem away. Car is running like a champ now. Thanks for the info BlackTuner.
Really enjoying the UTEC, very happy i made the purchase.
And i totally agree with Sharif, i would not try to tune a FI car at this point. Much much safer to tune a NA car.

I think your knock thresholds are too sensitive. You probably will want to desensitize them in the 6k and above area. I would reduce it by about 8-10 point in the knock constants.

With Tuner it goes like this
Serial cable from UTEC to Tuner

With Out tuner
Serial cable from UTEC to laptop
Or

sounds good
i am taking a hard look at this
aceman....do you know how much hp you gained before and after the utec?
also, do you need a reflash in addition to the utec, or will the utec have the same effect as the reflash?

I hope to get to the dyno this coming friday to find out.
I had the reflash prior to the UTEC, but that was only because there was no UTEC at the time. To answer your question. No, you dont need to have a reflash.
There are many tuners now that can tune the 350z with the UTEC. And with the tune you should make more power than with a reflash. Its also better to have the tune done on a dyno. But i have been having a good time trying to do it myself. I have learned so much in the past 3 weeks. Thats part of the reason i decided to try and tune the car myself. I work in the computer field and i love to mess with anything computer related

i have seen other ecu programmable units...cool to play with even if you are not a computer person
well...be sure to post those numbers...i am very curious how much you gain with your mods which are similar to mine

When you tune the UTEC on a Dyno and datalog, you will be able to see the points on the dyno graph in relation to the data logs, in which you can improve.Some cars improve a little, some cars improve ALOT..
So, if a motor quits making power from added timing, would there be any real advantage to a 100 octane N/A map? I would assume that you would need more timing to get back to where you started due to the slower burn and you could maybe run a little leaner, but would it make any more power?
I'm sure I'll end up trying it just to have something to play with after I get my 93 map right.
...and, since this has become the official DIY tuner thread I'll attach my last log graph. It had a lean spike at 4750, due to an overcorrection on my part, but I think its been worked out since. Should get a new log this weekend.

We found that 116 octane fuel on NA cars, even with very aggressive timing advance, did not result in a meaningful increase in power. This was just one example. I am sure another engines might respond differently, based on the mods done.

You dont really need the Tuner unless you plan on dataloging your own A/F and doing your own tuning.

Here are my before and after dyno's and the log file for the after dyno.
Looks like i made 4 more HP and 5 more TQ over the reflash. I think i can pull alittle bit more out of the car with more tuning. Had the A/f dip to around 12.5 A/F and it did not make more power with my parts. For my car after about 7 pulls on the dyno, i made the most power with my A/F around 13.0-13.2.
Also my timing was to far advanced. I made more power just advancing the timing between 1 to 2 degrees. I need to play with my A/F alittle more. Around 6000 it dips down into the 12's. Need to bump that up alittle.
All in all i am happy with the results. The results are on top the AAM reflash.
More to come later.

That dip in the dyno around 3000rpms can be smothed out a bit.By the looks of your data log, your in the 12's a/f at that point, go with mid to high 13's and keep it mid 13's..Other than that nice job.

Would like to add that i had a blast tuning my car on the dyno. The guys at Motorsports Performance in Frederick let me sit in the car and adjust the maps before each run. I guess i did about 8 runs and let the car sit for about 5mins between each run while i changed the maps around.
I did do a data log for every run that i did on the dyno. I do believe i am the first one to post up a dyno with a data log
Good stuff Later
