Doing a little surfing yesterday and came upon a guy who has a 1988 Lancia Delta HF Integrale: 2.0l turbocharged.

He's using the SMT6 to control fuel and timing, but hooked it up a little different.

Instead of hooking the TPS to the deflection scale .... X axis. He set it to the MAP sensor. Interesting setup, and he seems very pleased with it.



... current MAP deflection (horisontal) and RPM (vertical). All grids are configurable. I set 22% MAP to be idle vaccume, while 48% is about 1 atmosphere. Above is boost, below is vaccume. 86% is about 0.8 bar, while 11% is max vaccume (engine reving down and throttle closed).


His setup is below and is making around 220whp ...



Trim 50 Turbonetics hybrid turbo
yellowprinted: Pistons, conrods, flywheel, clutch, ..
Bazza flow-upgraded valves
OMP Group A exhaust
16v injectors
2.5 bar MAP sensor
Fuel pressure 4.5 bar
Current turbo boost 0.8 - 0.9 bar
This setup really seems to work on the 8v, and clutch slip is pretty common :/


SMT6 Set is shown in attached photo.

So is this an OE turbocharged car? Is he modifying the OE MAP sensor signal as well as using it as the deflection input?

interesting, but the image is damaged by jpeg compression ... got a link to original image? or to a forum discussion?

Here is the link to the guys page :

ah!!! there you go ... the image looks LOT better!

Thought I'd bring this back up ... seems like a very interseting way to tune the car ...

And the Link (http://www.lovaas.org/Content/Lancia/smt6.html) to the guys site

and his work ...



My SMT6 setup for the 1998 8v Lancia Delta HF Integrale:

Bazza flow-upgraded valves
OMP Group A exhaust
16v injectors
2.5 bar MAP sensor

Current turbo boost 0.8 - 0.9 bar

A sample playback file from my Integrale. With this you are able to view about 30 minutes of "realtime" fuctionality of the software:

Graph showing boost and rpms
Graph showing RPM (yellow) and turbo boost (yellow)..

This is an example of how the SMT6 windows application looks when running..

A short description of the application: The SMT6 from www.perfectpower.com is a plug-in ecu for most "modern" engines. What it does is allow you to override sensor/ecu readings for best possible fuel echonomy and or power output. It also has a lot of other goodies like extra injector(s) configuration, NOS, water injection, rpm limiter, boost limiter, ignition limiter, 2 maps (switchable), ..

The reason I bought the unit was mainly the price. Buying stand-alone ecu and/or making a new chip for the current setup is too expensive. + with this setup, I get to learn a lot about how injection/ignition systems work. If you get lost, just reset all values, and you're back to the original ECU functionality.

What's this screen?
First of all, the analog injection map (the main grid). In this grid, you alter the values for overiding analog input (MAP, TPS, MAF, ...).
Analog output is calculated by the following formula:

Ana.Out=(Ana.Inp+-Offset+-X)*Eng.Tmp
Analog input: sensor input in volt. 0 - 10 Volts
Analog output: output to ECU in volt. 0 - 10 Volts
Offset: Set in the global settings.. Analog offset.
X: Grid values: -127 to 127
Engine temp: 0.0 to 1.0 (Hot engines require less fuel or something)

The left side of the screen shows input/output/override values. This view is configurable by pressing the "Setup Display" button.

The lower graph shows graph realtime.

Description:
AFR values are Lambda sensor values. The second screen shows lambda input in yellow in the graph selection. Current setup shows 13 to 16 lambda..
The yellow markings in the main grid is current MAP deflection (horisontal) and RPM (vertical). All grids are configurable. I set 22% MAP to be idle vaccume, while 48% is about 1 atmosphere. Above is boost, below is vaccume. 86% is about 0.8 bar, while 11% is max vaccume (engine reving down and throttle closed).

in dmdicks smt6 thread over on newtib, it has the wiring set up with no tps. now to wire mine like that, but keeping the turbo box i would wire the turbo box normal, and just not connect the tps wire to the smt6 deflection in right? i would much rather tune of the map sensor instead of the tps.

Sounds right to me, but can't you use the map input in place of engine temp and then use it as a multiplier.

The engine temp is a little more complicated than that as its an inverse input. Meaning as temp increase voltage decreases and vice versa.

I thought you could set your voltage settings through the DOS window? Wouldn't that allow you to use the MAP sensor readings and run them through the engine temp multiplier?

I was going to do it that way ... as boost increases adjust the fuel. With no boost I could run a leaner mixture, then as boost comes on increase fuel to richen it up as needed.

You can adjust what is displayed at what voltage using the dos commands you'll just have to remember its an inverse reading. 5 volts will be at the bottom of the column instead of the top.

Thanks for the info ... so what do you think about using the MAF setting in place of the TPS signal? Would a MAF, RPM and MAP setup be a better way to determine engine load?

MAF in place of throttle deflection (Y axis) and boost in place of engine Temp and used as a multiplier ... rpm would still be the X axis on the bottom.
