In comparison, my Honda map averages 2.7 in/hg resolution. Like I said you don't need a MAP sensor to tune NA, but it definitely should be an option for those of us that prefer MAP sensors.

have you datalogged any runs. it might be picking up some knock(probably engine noise if you are NA) i would turn down the sensitivity just a bit
i think mine are set to 100 90 80 80 65 65 65
your car was knocking at 05 i have had nitrous knocks and NA knocks but nothing ever past 01. even with the sensitivity all the way up at the base map settings..

Seems as if my car is Knocking more the richer i go. Here is a little bit of the log. Have it set as close to 12.5 A/F as i can get it.

thats crazy, all the datalogs i have done, i have not seen any knock over 01
i hope everything is ok and you have your sensitivity down low on your upper rpms... hmmmm

That's probably something one of the professional tuners with experience would have to answer.
You could find a Sunoco with 100 octane. If that gets rid of it, it was probably a real knock. If not, its just engine noise.

I will give that a try tonight.

Started messing with the timing. Insted of having everything set to ECU i went ahead and set the timing map as follows:
3000 = 25
3250 = 25
3500 = 25
3750 = 25
4000 = 24
4250 = 24
4500 = 24
4750 = 25
5000 = 25
5250 = 24
5500 = 24.5
5750 = 25
6000 = 26
6250 = 27
6500 = 26.7
6750 = 27
7000 = 27
With the timing set like this i get a hickup around 6000 and 6300 rpm. I have this section in bold. So since this is happening, should i back down the timing at this area??
Here is my latest log. Trying to get a 13.1 a/f down to 5800 rpm then go to 12.5 a/f. Looking good so far.

i have a question...if you buy this thing can any tuner use it or does this person need to be certified by UTEC?
this thread sounds like more of the home user tuners...but i would like to take mine to a reputable tuner and let them work with it
also, is this better than getting a reflash...in a sense you must tune yourself to get what a reflash would give you
thanks in advance

After reading back through the manual, it looks like the UTEC detects knock and then retards the timing. If you have everything set to ECU the UTEC does nothing. Either i need to turn down the sensitivity or back down my timing at those locations.
Anyone else have any imput ?

i sent ya a pm about the knock
no anyone can tune it themselves after a lot of reading and trial and error. i would recommend having a shop do it or it least show you about it first if you are new to tuning stuff...

this thread sounds like more of the home user tuners...but i would like to take mine to a reputable tuner and let them work with it
also, is this better than getting a reflash...in a sense you must tune yourself to get what a reflash would give you
thanks in advance
