My latest t-link data with new chip-Joe L.

[SuperTTA]

Hi all, especially Joe Lubrant, if you are looking. I put in the reprogrammed chip for my car...thanks a bunch.
Here is a few runs I did today. It was in the high 60's, low 70's today, nice.
I do not know if the columns will line up to be able to read this stuff. I am running about 15-16 psi of boost and 44.5 psi fuel pressure. Let me know if it would be better to send the t-link files(they are in the document format)
I am still getting some knock, especially if I lay into the throttle when going 40-50 mph and the boost comes up to 16 psi or so...goes over 10-12 degrees of kr. I thought this data might help.

What did your car run? Just curious. I never see many Turbo TA run. Especially a near stock one.
Thanks

 

[SuperTTA]

Sweet,
Never took her to the track. I've done some 0-60 times using a g-tech and get anywhere from 5.0 to 5.9 seconds depending on the time of year. 5.9 was after driving 45 minutes in 95 F here in Houston. 5.0 was about 40F after driving 20 minutes. That is running 16-17 psi of boost. Stock is 16.5 psi boost.
1/4 mile should be around mid 13's to at 100-102 on pump gas and 16.5 psi boost. I've heard of some stock ones running 13.35 and some run low 14's. Some are spunkier than others.
I just want to get the car sorted out with no knock right now while it is cool. Heck when it is 95 F out I probably will have to drop to 14-15 psi boost. That stinks.
My main problem now is I cannot run more than 15-16 psi without knock. Where a year ago I could run 17 without knock...maybe 2-4 degrees. Only thing I really changed was to a S.S. maf pipe.
Later,
James

 

[Sweet6]

Good Luck with your car.

 

[JayC]

Are you using the Turbolink boost sensing setup?

 

[SuperTTA]

Jay,
I have the cable, but not using it. I should of bought a second map sensor. I have been afraid to use it for fear of losing calibration my in dash boost gage. When we used it on a friends car his boost gage pegged 20 psi and stayed there.
I was going to t off the vaccuum line and run two map sensors.
I would say my gage hasn't changed only for the fact when I can run 17 psi, my car will bust the tires loose on asphalt at about 20 mph. When it is 15 or 16 psi, it will barely squeak them or nothing....I know that is not scientific, but that has been the way the car performs since I have had it (1996)
Any advice?
Later,
James

 

[JayC]

Actually I was just looking at your MAF not going to 255 and that's a byproduct of the Turbolink boost cable but since you aren't using it, that's irrelevant now.

 

[GN owner]

JayC,

I have the T/L with boost sensing harness but I haven't installed it yet. Are you saying that once the harness is installed it will affect the MAP gps reading? Thanks for any info on this issue.

 

[JayC]

Under the right situation it can.

 

[SuperTTA]

Jay,
I noticed that I only show one frame of the maf at 251. My maf readings are usually higher when I run 17 psi. At 15 psi I do not see it go much over 235.
I thought someone mention to me that the MAF usually doesn't max out at 255 till you are putting out 17-18 psi with the stock turbo. I am incorrect?
Later,
James

 

[JayC]

That's more dependent on horsepower level than with boost levels really so it's going to vary from setup to setup.

 

[J. Lubrant]

Not sure of all the potential problems, but first thing I would do is get that TPS down to 4.5 to 4.65, instead of that scary 4.92 volts you are currently running Seen to many cars go crazy with that high of a tps setting.
For lack of any technical term, the closer the tps is to 5volts the stupider the computer gets.

Secondly I would get, borrow or steal a known good and I mean provenly good MAF, and see what happens.

T-link although a great tool, misses a lot of things between frames, but in any event if you have knock most of the numbers turn to crap and the car loses power hence posibility of lower maf#'s

Also best to record car from dead stop instead of from a roll in my opinion. Knock can occur from a roll due to hard downshifts or tire spin etc.
Seems like most of the knock occurs on the shifts, could something be banging or hiting the frame etc. or bad Motor mount?

Also not sure of the timing provided to you, I seem to do most at 20 deg. some cars can tolerate it some can't? You could be a case where 18 needs to be used. Remember chip commanded timing is just that commanded, but might not be what is actually occuring due to alot of other variables etc.

Just some thoughts for now.

Hey Joe,

Are you still gonna do chips for PTE or is someone else in-house doing them now? Sure hated to see you leave....

Good luck!

 

[SuperTTA]

Hey Joe,
I noticed I didn't put my last name on the posts. This is James Wicmandy. You programmed the chip for 17-18 degrees of timing. It says 92 octane, 17-18 degrees on the chip.
When I set the tps with the car off, I was in the 4.7 range for the tps. I didn't realize it was that high until turbolink showed this.
I will readjust.
I just changed the fuel filter today, and I am going to test the car tomorrow. We will see if there is an improvement. I noticed my fuel pressure went up 1 psi just by changing it. The old one had about 12K miles on it.
I will try and borrow a MAF, but on one run it did show 251 on one frame. I did borrow a brand new GM maf about 6 months ago and didn't notice any running difference, but I didn't do any t-link runs.
Your leaving PTE? That stinks. You need to send me a e-mail address so I can bug you in the future. LOL.
Thanks for all your help.
James

Hi Russ,

I sure hated to leave there also, great group of people to work for and with.
I will always be associated with PTE in one way or another.
Harry, Dan, Jim, and Daisy & yes even that Pat fellow, were not just employers & co-workers but considered my friends.

I will still be consulting with PTE regarding any matters they wish me to, which would also include chip programs.
Although I will no longer be there on a day to day basis as before,
I am sure that Harry or myself can assist in any chip programming needs.

Thanks for the Good Luck, as I always can use some.

Joe

Ok James,

Just for curiosity check to see what your maf reading is at idle with the car fully warmed up...both in gear and in P/N.
I usally like to see 5grams.
How is the car idling? If its a little rough or hunts for idle stability, disconnect the maf connector, if the engine runs smoother, its also a pretty good indicator of a bad maf.

Do your tests as you stated and let me know, you could also add some octane, like 100 to your gas and see if the knock goes away, than that of course would tell you that your getting some crap gas less than 92 as advertised.

Doesn't the fuel look a little rich here when compared to the air flowing according to the maf numbers??

 

[SuperTTA]

Joe,
My MAF reading in P/N is 5, when I put it in drive I think it goes up to 6. I disconnected the MAF and it runs the same. I did a test about 5-6 months ago with a brand new GM maf and it idled the same as with my MAF.
I do know that with my Maf I need to leave the screens in it otherwise the car will idle like crud.
BTW, my Maf is a remanufactured maf I got from Conleys about 2 years ago.
Thanks for the help.
Later,
James

Nope, not that concerned at this time. 810-820 would be what I would like to see for street pump 92-93, but other things may be causing the ever so slightly richer numbers. No big deal at this point of time.
I am more concerned with knock than the fuel,(o2#) BTW never ever go to the bank on O2#'s alone.
I also wasn't happy with o2 counts or delta counts as they seemed slow to me. Maybe not a very active O2 sensor either.
I will see what other feed back he has after more test runs, before jumping to any concrete conculsions.

Joe

Joe, I agree 810 on a street chip is fine, but I was refering to these numbers in particular, they look a little rich when compared to the lower maf numbers.
