I feel a little more encouraged.....

was "offered" some SD 60 settings to "try", and by golly it looks like you guys were right...issues are in the tune it appears.

Don't need a gas mask...

I bought a new set of intake mani gaskets, don't really expect that to be an issue, but for the price and an hour or so of free labor I thought it worth the effort. Will swap those out tonight and...

The engine does idle, it just stinks to high heaven and playing with commanded AFR and timing on the VCM controls does not lead to a "sweet spot".

All I am after is a little help with idle area's...

So short of ordering the DVD can I get some help on this injector data?

I am still not convinced its the "only" issue I am dealing with. If someone can help with the incorrect Injector data enough...

Sounds reasonable. So I guess I need to find said data.

Once the injector data is up to par, I assume run through the RAF drill a couple more times. Then attempt to get the VE dialed in at the...

That is a bit confusing. So some of the data needs to be updated, but not all?
Of course that is way above my paygrade, so......:pray:

Would these injector setting only become an issue due to the...

Config file posted....

looks like STIT data was scanning??? early on in the idle log running in the10's but I don't understand how, I thought this was turned off in the tune???

Was wondering...

Siemens 60's

Last pro tune I had done, supposedly had the latest and greatest 60's data uploaded??? not sure if it was Gregs data or not??

I can tell you, that with the last cam the car ran and...

up on blocks, but haven't torn it down yet. most likely won't have time until this weekend.

As for the tune, don't look to far beyond just the idle area's. I did drive around the block just to get...

I guess a tear down is in order. Car is back on blocks, putting the old cam back in for giggles and see what happens.

:shrug:who got the 5 bucks....

I'll just throw this out there for discussion, I have no idea how it actually worked. All I know is that I had an issue awhile back, but I thought my car actually fired but wouldn't run.....don't...

Before I do something drastic......ie pull the motor back apart. I thought I would see what you guys think of this issue.

I changed....

Old Cam: 224/232...

Rinkrat, thanks for the links and your work appreciate the input.

I have resolved the issue, and its an embarrassing one. My MAP sensor was not hooked up!! My regulator's fuel return line is right...

I went through this drill last night, the only thing that changed is that I now need even more ve to keep my AFR anywhere near low enough to support combustion.

At this point I am assuming I have...

Thanks for the link, looks very thorough. I will spend some time looking it over.

I still a bit in the dark as to why such a drastic change in VE from one performance cam to another. My old cam...

Car has been down for quite awhile sorting out valve train issues. previous tune was spot on pretty much across the board, from start up, thru warmup, and on down the road. After sorting out my valve...

Bringing this back up, cause it still aint fixed!!

I pulled the front end apart and checked cam install. it appears the intake is roughly 2* retarded from the cam card, exhaust is right on....

Not sure what is causing this. After an ECM flash, the next attempted engine start is awful. The idle goes very lean, car will start, stumble, die. I have to play with the throttle and as many as 6-7...

Well it was a thought...thanks for the insight!

I guess I will just stick with idiot lights, and my IAT controls to hopefully keep the engine intact.:pray:

Not familiar with COS? I am running a 2 bar OLSD tune.

So based on the Knock sensor idea, how is this theory...

Old thread but same thoughts I was having. wondering what parameters the ECM must see to switch to the low octane table?

I am currently using IAT to control timing in the "high octane" table. I...

Awhile back I had some issues with the SPAL fans installed in my Procharged GTO. Essentially the 16" fan was toast after about 2 years of use. The short version of the story is SPAL suggested a PWM...

Thank you for your reply...

I do have a completely custom, boost referenced staged twin pump fuel system regulated by an SX performance rail mounted regulator. until I am at 3PSI boost, the intank...

I have tried everything from whole numbers only, all the way out to 9 decimal points......no effect.
