OK I tried the suggestion from a thread right above - went to the program files folder, set the Properties (right-click) for the scanner program file, to "windows 8 compatability" mode, and "execute...
Like it says, after the update the scanner won't connect, it puts up an alert saying it can't validate (don't recall the exact message) after it's started reading info from the PCM. Prior to this I...
You're right, the vette multipliers changed a lot also, that one was a bad example. The fbody multipliers are the same though, 98-00 vs 01-02, but the max airflow values are different by 2X. I've...
Not really expecting anyone knows the answer to this, but anyway...
closed loop proportional airflow - why is there such a big difference between 98-00 fbody, 01-02 fbody, and 00-02 vette?
98-00...
Newb question (for Ford, I've been using hptuners for GM for a long time). Is there any support for "intelligent key" programming? This is for a late model Taurus, for which I only have one key, and...
e-brake is applied, as well as regular brake, and definitely at operating temp (I wouldn't rev it that high until oil is fully at temp). Any other suggestions appreciated.
I posted this in the gen3 v8 forum but then saw this thread which is exactly the same problem I'm having:
I've tried 3 times so far to do a crank relearn, but I get no indication that anything is...
I've tried 3 times so far to do a crank relearn, but I get no indication that anything is happening, it just revs up to redline. First I click the "crank relearn" button, and get a dialog saying to...
Well if that's the case then that's not what was happening in my scan, since I have stock cats and rear o2 sensors.
I noticed in a recent scan that in the middle of an extended idling period, the commanded afr suddenly went lean (15.75) and o2's pegged low for 7 seconds, then went rich (13.98) and o2's went high...
This seems like a (minor) bug:
version: 3.2.137
car OS: 2000 fbody
computer OS: windows XP
In the editor, open IAT Spark table, and also open a compare file for the same year. Look at the main...
At the end of a logging session, if you exit without saving the data first, it should ask you if you want to save before actually exiting. Come on! this is just obvious UI stuff, I've never used...
If you think that's strange you should look at the 00 fbody table, #s 1, 4, 5 are different on the right side, with #5 being most sensitive, and the cells on the left look they were set by a choosing...
OK thanks.
Related question: the total misfires count will stay at the same number (like, 4) for some number of frames (like, say, 100), but it's a different length each time it happens. What does...
I'm logging misfire history cylinders 1-8, plus total misfires. When total misfires shows misfires (I get either 2 or 4 at a time), misfire history shows zero for all cylinders. So, are the misfire...
OK, well than this is confusing. I'm looking at the raw log data, which includes KR, burst knock, and cyl air. At the start of the first KR event (which lasts for 15 frames), the delta cyl air (frame...
Well I guess no-one knows, but now I came across some posts saying burst knock does not show up as KR, it just pulls timing... is that right? So looking at BK won't help solve a KR problem?
Trying to track down a knock retard (tip-in) problem. I thought it might be burst knock, but logging BK it's alway 0. To double check this, I'm looking at logged dynamic air vs the values in the...
Airflow -> Dynamic -> Dynamic Air Flow -> Dynamic Air Filt
"Filters the current airmass before prediction filtering. If in steady state the current airmass value is MAF based, if in unsteady state...
Well for the record it now looks like it's not the maf after all, since it's started having KR in SD mode. I guess I'll have to put back the exact SD tune/OS that had 0 KR, which is before the VE...
Interesting - the honeycomb is definitely less obstruction than the stock screen, but should do a good job against turbulence, the cells are much longer than the stock one. But maybe it's just...
Maf is screened, but it's one of those honeycomb screens from saxonpc.com. Anyway if that's the cause wouldn't it affect the fuel trims?
I'm getting bursts of knock retard but only when the maf is enabled, not in SD. This is in closed loop, not in PE mode, low rpms (1800-2400 area), tps around 30 after ramping up. It is not a lean a/f...
If I switch my 2000 OS to "1 bar SD enhanced", will the maf still work? There's no "MAF enhanced" OS option like I've seen reference to here. In the SD enhanced I still see the maf table, fail freq...
