Yea it did help some but at temp without any load on the electrical it will still begin to surge although not as bad.
I wish we had a throttle body scaler parameter I think this would cut down the...
I know that one of the knock pids are goofy I keep meaning to remove the one that is goofy but I forgot.
Yea I am finding the pids do some funny things.
On a side note I have taken the low octane tables and smoothed the idle area (it had a nasty jump in one spot) I copied the high to low in the idle...
Ok,
So I have noticed that the closer I get the fuel trims to 0 without any load the worse the surge will get. So I reverted back to the additional fuel at idle and noticed also that if I turn on...
Ok here ya go Joe
Included a log of idle and it should show it surging and whatnot.
Also here is a log of the cruise home.
It is extremely jumpy in 1st and second gear, if you take off easy no...
Well just need to tackle the hunting idle once in awhile and I would be happy.
Looks like the only table is the injector vrs map scale, since mine has the 60 Siemens injectors I wonder if doing...
Well for the record I am not complaining about it I am happy to be able to tune the multitude of vehicles and joecar has always been extremely helpful to me and has helped me out on many occasions....
That would certainly be a bummer.
I understand where you are coming from as the software has been great with all the other vehicles I have tuned. Once going into the 4 cylinder realm though there is not very many tables at all that...
Ok well I have discovered that the P12 uses KR not KRKRET hence the false read outs from that one being selected I believe.
No I'm just saying that I only am logging kr in my normal log but when I replay the log I am seeing kr and also knkret pids. The knkret pid just doesn't seem to make sense because it displays from.8...
Whats wierd is when I am recording all it shows is the kr which registers nothing for most all of the drive. A little knock (1.4) when accelerating on the highway before up to temp then it backs...
Hi joe!
Strictly 92 in the car from shell or chevron. NO cheap stuff. I know none of it is the best anymore though.
Guy I have been logging and dialing in my maf on this cobalt SS and I have ran across something that has me wondering.
2007 Cobalt SS
2.8 pulley, 60lb injectors, dual pass,LS4 TB, ZZP intake,...
Thanks for the help!
I think with some timing added to the table I may be able to squeak a bit more. It would be awesome to be able to knock down 20's out on the highway!
So I thought I would give an update. I have slowly been creeping up on the fuel table and am almost complete with that side now I believe. I filled up after running thru a tank of fuel and I had to...
Yes it still has the factory cats and exhaust on. Maybe cats are changing afr for the readout on the wideband?
Is the rear o2 not a viable place to put the wideband? Or can I do this but make the...
The Afr appeared to be working correctly. It was constant 14.4-6 for most all throttle levels until the pe activated.
I am thinking the pe ramp is just a bit slow. It did go and I was able to achieve 13.2 for a very short period. I didnt really stay in it though to find out.
I fallowed the filters on the thread....
Maybe this would be the wrong way to go about this but what about just adding a small amount (1-3%) to the lower rpm portion (under 4k rpms) to get the ltft a little more in line? Working in small...
Right now I am on a 6.0L 4l65e in a denali so similar in some respects.
I have found that the transmission tuning and torque management decrease really makes things come alive and feel so much...
So I hope this will be an ok start for a log. Do you guys agree that it could use more fuel in areas?
I didnt zero out the burst knock yet however I did not notice any kr to speak of
Saw the...
no Im not seeing any kr but I believe the spark tables are very lazy. I think I will copy in the ls1 Camaro spark tables after getting the fuel a little more in order and see what happens.
Just...
I know this doesnt pertain to the fuel tables but do you normally zero out of the burst spark timing when tuning? or do you leave them alone?
Also would I be better to change the O2 to 450mV?
