Anyone running speed-density on a hot air??

[turbonut85]

Just curious if anyone is running a Turbo Tweak speed density chip in their hot air...if so, post up some details...i.e.: location of the sensor, what's required, how it performs...and things like that. Thanks. ---Keith

From what I was looking at it looks like all that would need done is run the wideband and the map, I would say map tie in right where the Hobbs switch is or use factory map, and I've had good luck so far with my wideband in my downpipe.

Speed density was one of my next ideas lol

Keith,
About 3 years ago (May 2008) I did some testing with a HA TT SD chip.
I know the SD chip is MUCH better now than before, but even the old version was awe inspiring! It will give you full control over just about anything you can think of.

I have a local buddy that runs the SD chip on a 100% stock longblock in IC'd car. Idle is smooth as glass and the car runs strong!

You will LOVE the chip!

Is there a lot of tweaking required out of the box with an SD chip? Or is is as simple as setting your baseline and going for a test run?

It depends.
When you have a set-up and break new ground, it will be close, but you can adjust just about anything you need.
Don't think Eric will mind if I post this since it is located on the public domain.
Here are the features. :redface:

1 WOT Fuel-WOT fuel all gears, above 13psi
2 1st Gear Fuel-WOT fuel offset for under 35mph (1st gear)
3 WOT Spark Advance Low Gear -Spark advance adjustment for 1st/2nd gear (use an odd# for alky)
4 WOT Spark Advance High Gear-Spark advance adjustment for 3rd/4th gear (use an odd# for alky)
5 Mid Boost Fuel - Fuel in the 0 to 13psi boost range
6 Low Throttle Fuel - Normal driving around fuel, use even numbers only. If a wideband is attached to Powerlogger, use an odd# to enable C/L.
7 Overall System Fuel -Similar to adjusting fuel pressure
8 Highway Fuel -Fuel during highway cruising conditions
9 Idle Fuel - Fuel when RPM is under 1300
10 Cold Start Fuel - Fuel during cold startup
11 Spool Fuel - Adjust how fast fuel ramps in with RPM
12 TCC Forced Lock MPH - Force the converter to lock at this MPH (128 turns it off)
13 MPH Threshold for 1st gear fuel - Used with param #2. Signifies the end of 1st gear fueling
14 Mid/WOT Boost Threshold - Boost level that decides between Mid Boost and WOT
15 Target A/F at Mid Boost - Target A/F at Mid Boost, Closed Loop (99 turns off C/L) Use only if wideband is attached to Powerlogger.
16 Target A/F at WOT - Target A/F at WOT, Closed Loop (99 turns off C/L) Use only if wideband is attached to Powerlogger.
17 Knock Retard Ignore - Knock retard ignore threshold Odd numbers are time, even numbers are mph
18 SES Shift Light RPM - SES light comes on at this RPM
19 Target A/F at Idle - Target A/F at Idle if using closed loop
20 AE Fuel - Acceleration Enrichment Fuel
21 Reload Defaults

I've been running the TT SD chip and I really like it! As Jerryl said it give you far more control than any other chip that I've seen or used.

You'll need a wideband on your downpipe, MAP sensor, MAT Sensor, laptop computer, Powerlogger and I'd suggest a scanmaster as well.

It runs pretty good without much tweaking, but you'll want to learn and tweak it to get the most out of your car.

i should look into this if i stay turbo buick powered. it sounds worth it.

Sounds like I'll need to spend some more $$$....:redface: :biggrin:

I hear ya.
Just look at #20.
It’s like adjusting the acceleration pump on a carb with a few clicks!

Heck with this chip, as long as you stay within the adjustment parameters, you can change injectors or fuel type, and adjust for them.
It's fantastic stuff! TT ROCKS!!

Jerryl: I don't have a hot air car but I do have the TT SD chip and it is a very good piece of technology for our cars. Sold my MAF and translator to buy the chip and had money left over to buy some race gas.

I'm the only one in OKbuicks using one but I've sure made some of the other guys take a hard look at their TT 6.0's.

Hope to see you and several others at Noble this fall.

Hey Phil,
Now that I have a running car , I can start to plan for it.
Hopefully, a 15 second car will help the cause.
