I'm confused, are you trying to fail the MAF and run in speed density? The PID in your log says the MAF is failed but it's definitely not failed correctly in the tune. You should probably put your stock timing tables back in too, those don't look great.

Your fuel trims don't look too bad though. A touch rich but nothing that would cause your issues

hey mate yeah its maffless tune ive been to 4 different tuners but just have stupid problems

[rabbs88]

Try this out. Just failed the MAF properly and returned timing tables back to stock. Post a log when/if you decide to try it

[troyjago]

okay mate thanks heaps il give it a log tomorrow

Give this tune a try, I made some injection timing changes and other small tweaks that may help your idle problem


MAF Failed + Stock Timing + EOIT.hpt

What is up with the BRAF table?

OP you have the original unmodified tune file? Compared to the OE file I have yours has ALOT of stuff changed that shouldn't be, and a lot of jacked up shit otherwise.

Hey mate I don't have the unmodified file as I brought the car already tuned but had problems so since been to 4 different tuners trying to sort out these problems, I just want to be able to drive my car and enjoy it

Thanks heaps mate il give it a try and do some data logs

okay so i tried them files above but got idle hunting and not starting great, ive decided to run my dctuning file as it starts and runs the best i just have a few little problems to sort out. #first idle seems abit rough and keep getting alot of timing swings on idle even though i cut down my adaptive idle settings alot and second thing i get weird surges sometimes on low rpm and at the same time see the timing move tables and last thing it feels a bit sluggish taking off but not that bad. here is the tune file and log

cammed-ve-ss-manual-troy_DCTUNING_v7 (2).hpt

dctuning-v7-datalog1 (1).hpl

here the tune file with spark adaptive cut down and a couple logs

new idle log.hpl

new log 1.hpl

new log 2.hpl

It's still a train wreck. Why would your VE table go to 175 Kpa if the engine is normally aspirated? You can edit the X axis and you'd have great resolution.

Why would you have +8/-8 degrees timing in your zero RPM error table?

Why are the over/under tables so aggressive?

It also looks like almost ALL of your idle adaptives have been modified.

I suggest you pull a file off the repository, put most of everything back to stock.

The tune is VERY rough? sorry 4 tuners have messed you over?

It would be better at this point to start from a completely stock file. Some dumb change someone made at some point could cause a lot of headache down the road.

It's about impossible to just look at a tune and can tell if it's all stock unless you find an exact same OEM file.

this is best i can do to get back to stock so u can start fresh with some tables your ecu is same number as mine but mine is HSV LS2 so is slightly different with heads and stock camshaft but its close as i think u will get to a stock i just copied all from my stock over to yours

[troyjago]

Okay mate thanks so best bet is to start from this file and catalog??

[07GTS]

if u want to use the SD tune then i went thru and setup as much as i could to be stock just fueling and some minor stuff i left, see how it goes, also change ur VE in scanner to suit the new layout, im not sure on actual fueling so make sure its good as ur testing not sure if u have WB or not
