I've used HPT for 10 years. I just "upgraded" to 3.2 and am finding it's like I'm starting all over building configurations and navigating the maze of options. For instance when trying to open the...

That did not work with or without STFT in OL using those settings. :( Seeing the car goes to open loop at WOT from the PE throttle position sensor settings but not at idle with "0" PE throttle...

I'll give it a shot although it would seem an earlier PE enabling would kick it into open loop easier. I posted on an Australian board as I know that a lot of them run SD and they may have had an...

No help huh? This is driving me crazy. I've attached a new tune. The one above had STFT in OL which of course wouldn't work. There has to be some way of getting OL idle and STFT driving or am I just...

In charts right click and select settings. There will be options with one for F or C. Do that for each you want to change. In histogram there is a button between 12 and the + sign. That gives you...

Having the usual idle problems with a SD tune and OL with STFT. I have a cam with high overlap and it comes down to an idle perfectly coming to a stop in pure OL reading a higher AFR than stoich....

ignore those comments then. there are people here that will help. ask over on LS1GTO too as there are some tuners there too.

i changed tires and decided to recal my speeo. my old Nitto 275s were 25.66" and the new Firehawk 285s were a published 25.97". i checked the speed with my GPS and it showed that the speedo was...

that's true for tuning without the MAF but you want to put it back unless you're running SD without the 1 bar enhancement

i have my warm engine IAC count at ~40. you need it above 0 a bit so it has room to adjust and obviously not too high so it has room up there when it's cold

so is Heidi Klum but i'd ask anyways :D

cool. i know on my '04 LS1 GTO my stock VE table was pretty rich and SD tuning made quite a bit of difference.

interestingly the only pollutant i know of that a lean condition will cause is nitric oxide. nitric oxide is in automobile exhaust and plays a major role in the formation of photochemical smog if you...

you can set the MAF fail frequency to "0" . take the MAF off and put it on the shelf

you didn't say what mods if any you have. typically a cam will give such fits as surging. surge can be timing or fueling. you need the fueling dead on to slightly rich in the low RPM and timing a...

it took me a few tuning sessions from cold to get mine right so you may have to do it a couple of times

have you changed your throttle cracker table?

ok, new one. real time tuning for air temp bias/filtering. it would make it soooooooo much easier to dial it this stupid table

plug in your unit and run the scanner. at the top you click on scan and then the MVPI at the bottom of the drop down. in the top section of the dialog box it has "write scan" and a warning that it...

did you load a calibration into the unit?

it's the one that "stops" the blade from closing all of the way over by where the throttle cable is. you need to back the screw out so the blade closes a little more. when you get it where your IAC...

PS, i fixed bucking at light cruise with timing (i added a little in that range) and making sure my AFR was dead on

do you have your throttle blade drilled out or adjusted more open than stock? it would seem to me that's it's getting too much air thru the blade and has no need to open the IAC controller. that's...

ah ha. that's why i posted the above. i saw that the VE was muddying up the whole thing. by blind luck i guess it seems i'm getting close to where i should be as the AFR is within acceptable range...

i'm not exactly sure what your asking but the MAT is a calculated number and the "scanned MAT" is just that calculation based off of IAT, ECT, bias and filter seeing as there is no sensor in the...
