Why are you only logging LTFT for Bank 1? Start logging both STFT and LTFT for BOTH banks. The one bank shows you are seriously lean... have you considered a vacuum leak somewhere? Try logging BOTH...
Need to log dynamic air, tps %, and why are your IAC counts showing "0" for the duration of the log... You started the log AFTER you started the engine. I would guess you have the throttle blade...
Blindsquirrel gets a virtual like..
Thanks for the feed back everyone. I've done some more testing.. Since it was idling okay, and holding good pressure for street driving using the factory narrow bands and STFT's, I put the NGK wide...
The band has to apply for 2nd gear... So either the band is OFF the servo pin or off the band anchor pin in the case, or the builder forgot to install the band, cut/damaged/missing sealing ring on...
I've been attempting to tune a truck that has a Corvette fuel filter/regulator on it. I have an intermittent issue idling. Sometimes it idles great, other times it just falls on it's face and...
Thanks guys.. I am going to send him over to Cesar at Horsepower Factory here in Houston. He has a very good reputation and I've not heard of any complaints against him.
here's the tune
I have a customer that has had his truck "tuned" by a local guy.. I went and read the reviews for the shop he had the "tune" done at.. Let's just say, the reviews are pretty bad. But, I won't base my...
One other thing that I like to do.. If you are going to be doing "regular" street driving while you collect your data, I find that the higher you set your cell count hits in the graph, the more...
Wait.. a crank sensor code... here comes the issue with the Amazon harness. I HOPE that putting a new crank sensor in fixes it.. If not, look at the harness! OR..... verify that all wires in the...
and he's running a FI Tech 92MM throttle body... I tried one of those... once... NOTHING I could do to get it to idle right.. As soon as I bolted on a Nick Williams-the engine ran perfectly. I spent...
You will need to add either the GM pressure sensor, OR a trinary switch such as what vintage air sells IF YOU WANT THE PCM TO CONTROL HIGH SPEED FAN OPERATION WHEN THE A/C IS ON. Please note that...
I looked through your initial post but did not see what stall speed your converter is... is it there and I just missed it...? Or, are you running a factory stall converter? If factory stall-that...
You do not mention what year your vehicle is, HOW you have the A/C set up-are you running a pressure sensor? These are the things we need to know.. Is this a swap vehicle? Variable or fixed rate A/C...
You have both long term fuel trims and short term fuel trims enabled. If you are trying to use narrowbands to tune the lower RPM range of the ve table, that's fine, but you should turn off LTFT's for...
On your idle log, you can see your fueling is off in the idle areas. Also, watch your spark, the fact that it is going back and forth is showing you that the PCM is trying to maintain a stable idle...
where is that like button again?... blind squirrel.. I hereby grant you one internet "like"...
and you are UNDER GEARED for 37" tall tires. Even after you get the tune sorted the 3-4 clutch pack is not going to be happy with that gear/tire arrangement. As mentioned above, just start over with...
Will the engine RUN if you give it some pedal? I don't understand why you are posting logs where the engine won't start, or dies instantly. We believe you... when you tell us it won't run. Those logs...
Maybe something like this;
IDLE OVER SPEED TABLE IS JACKED!!!! Fix that NOW.. Then, your IDLE SPARK "IN DRIVE" & "IN PARK" need to match in the 0-400-800-1200 columns, and then in the HIGH and LOW Octane tables they need to be...
BK2LIFE nailed it... It is recommended to start with a STOCK tune as a baseline and then YOU must go in and tune the VE & MAF tables to work with your engines configuration. Too many times "wonder...
Also, after finding where the idle stabilizes with locked timing, go out and lightly drive the vehicle and see if you are still having issues with the vehicle trying to stall when coming to a stop,...
