ok

U7193 V.9 2004 CHEVY TAHOE

ok got the log. IT TOLD ME TO INCREASE +2% AGAIN.

Ok so don't clear the code yet? Or clear it and do a new log?

I got a new issue. I noticed after 50 miles that the check engine light came on. I checked the code.. PO420 catalyst system efficiency below threshold (bank1) I do have magnaflow cats on and all the o2 sensors are all there but this never happened until I changed the injector slope to shot more gas ...

OK i WILL TRY THAT. i'LL DO ANOTHER TEST IN A FEW DAYS JUST TO SEE WHAT HAPPENS

i THINK i DIDNT DRIVE ENOUGH MILES BETWEEN THE 2ND TO 3RD LOG. FROM THE FIRST LOG TO THE 2ND, i DID AT LEAST 3 DAYS APART.

U7193 WITH NEW VERSION 9 ON A 2004 CHEVY TAHOE

SOUNDS GOOD. HOW DO i POST UP MY LOG FILES?

IF U MEAN DRIVING FOR A WHILE AFTER THE ADJUSTMENTS THEN YES i HAVE PUT ON MILES

iM DOING IT ONE AFTER ANOTHER WITHIN ONE HOUR OF EACH OTHER. bOTH LOGS WERE DONE TODAY BETWEEN 3PM AND 5PM AT 70*. wHAT DO U MEAN BY PUTTING ON MILES BETWEEN ADJUSTMENTS

Ok now im a lil worried. I did another test which is the second test and it said to go down 3% which now took me to -2%. I did another test and it said to go down 4%. Now im at -6% and I know I must be shooting aLOT more gas than I should be right? Could this be right or is something wrong?

FINALLY GOT IT TO WORK. NOW I PREVIOUSLY HAD MY INJ SLOPE AT -1%. THE DSLOG SAYS TO ADJUST INJ SLOPE UP BY 2%, SET THE FOLLOWING ADJUSTMENT ON THE PREDATOR TOOL: +2%. DOES THIS MEAN I PUT IT ON 1% OR 2% CAUSE FROM THE -1% WHERE I HAVE IT, IF I ADD 2 IT WILL BE POSITIONED ON 1%.

ok I have got the cable. installed drivers and ready to analyze but I get an error message while trying to analyze. access to the path c:\Programs files(x86)fgbsoftware\dslogredux\raw_data210022268.csv is denied.

yes I have the newer version. I did the logging process but now I have to buy a usb to serial cable. I'll get back to u once I do
