Time to start the tuning process HELP

The car is running Good but it smells rich to me.
I have
1-TT 92 chip (using 93)
2-340 Hot Wired
3-Adjustable FP Reg.
4-Scanmatser
5-CR43 or CR44
Stock everything else

So, where do I start and what do I look for?

 

[Dabigguy]

A good start would be posting Scanmaster data so we know where your tune is.

Make some cautious runs, get some data, see if it is in fact running rich, then you can adjust your fuel pressure.

You did good with the fuel upgrades and TT chip, but "stock everything else" can still run poorly and detonate, ask me how I know. Spent the first year with my car just trying to get it to stop knocking. Be careful on the gas pedal and watch closely for detonation on the scan master.

If you get any detonation you can then go into the TurboTweak chip and adjust fuel or timing to try to eliminate the knock.

More info for you guys

Do i make a few WOT runs to see the readings i get then start from there?

 

[TurboDave]

Mine smells rich at idle also. I do know however, that it's not. The WBO2 can be reading perfect stoiceometric values.
I believe that the "rich smell" complaints (and this is jus my theory) are on vehicles that are....well, lets just say, are missing the primary smog device under the car.

could be
but lucky for me 68 doesn't require one.

Not a problem here either, for any car. :biggrin:

First I would check your numbers on the scanmaster at idle
To the Recommended numbers at Idle before, I WOT.
IAC, TPS BLM's etc.
Then watch the numbers as you increase throttle
Unless you want to learn again how to replace head gaskets

TPS-42-44
IAC-all over the place
BLM-????????

If it doesn't rain too much tomorrow I’ll do some testing and posting.

Anybody?????
Or
Are the numbers perfect and I don't need to adjust anything?

I don't see anything too badly out of order there. I'd like to see a higher idle airflow though. 4 is just a touch low, should ideally read 5-6 (tending toward 6).

 

[TURBOPOWERED68]

thanks for the reply.
I just set the FP to 43ish WITH THE VACUUM LINE DISCONNECTED.
I made about 4 passes working my way up to WOT
And I made 3 WOT passes and NO knock on the Scanmaster.
The O2 readings were at 840 to 875 at about 80 MPH in 3rd gear.
The boost was in the range of 12-14 maybe 15 PSI.
The car still has a stock NON adjustable actuator and no manual boost controlling devises

 

[imjoesnuffy]

Seems to be rich. I would pull some fuel out via the chip. Try to get your O2s closer to 750-780 with no knock.

 

[TURBOPOWERED68]

the change would have to made across the board since i don't have a VSS.
Could this be a problem down low?

 

[imjoesnuffy]

Depending on what your O2's are in 1st and 2nd, it shouldn't be a problem. In my limited experience, I get knock in 3rd before I get it in 1/2 gear. Longer time for it to lean out in third.

Start slowly by pulling it out of the chip in small increments. 1-3% at a time, until you get knock and then back off.
