24 wires 16 for injectors.Cut & soldered and used heat srink made a nice tidy install.I installed box under dash.

Using same injectors as you ,just having a little trouble getting offset tables right.
Idle still great around 850rpm.

 

Did you get the latest 'ware from TSI?

Have you redynoed or have any new performance info? Last time I recall you doing 640rwhp running out of injector.

John in Chicago

 

Yes have latest software version 3.

Haven't been back to dyno as of yet.Been tuning on the street with my wideband and datalogger EFILive.
Want to make sure fuelling etc is right before redynoing.

Do you have any offset info for these Siemens Injectors.Im down to about 50% of the factory injectors offsets ????
My injectors at present seem to be running around 60% duty cycle.

 

Let me look around for offset stuff... Let me check with two buddies...

 

Is it at all possible to retain any functions such as ABS, TCS, and Airbags when you install the fast system? I'm going to be making some substantial power on a street driven car and I wanted to know if there was a way. Ron Duke once used the Daetech ECM which allowed him to retain these features for the street. I doubt he still has it but I know he did for a while. It's suppose to interface with the stock computer with four wires, puckng up the cam sensor, crank sensor, and injector pulse signals. I wanted to know if this was a practical option.

 

If Ron is running a standalone his speedo and gauges don't work unless Kurt rigged up a custom solution.

My TSI controller would fit your needs, since it's a piggyback and it's really only being used for fuel and spark.

 

You can run a FAST as a piggyback also (or any other aftermarket solution pretty much) - you basically just connect the stock injector outputs to resistors or leave them open - disconnect the stock timing input and connect it to the fast instead. Now the aftermarket solution basically controlls fuel and timing (connecting to it whatever inputs it needs). Depending on how you bypass the stock pcm you may throw a code - but it will be irrelevant as the pcm no longer has control over fuel/spark - ABS, TC, gauges, etc. will all still work per norm.

You could make the install uber-clean if you got an additional male-female pcm connector and simply interfaced with the stock harness, ran the appropriate wires to the FAST/re-routed appropriate stock wires, and left the rest alone as straight connections.

 

Let me ask this of the experts on this stuff.

Is the TSI box going to take changing weather conditions into consideration. I mean the stock computer can compensate above and beyond the MAF(to a certain point) but, it can't compensate for changing ambient conditions. Will tuning with the MAP like the TSI box does take weather(temperature) into account?? Baro pressure shouldn't matter since it will be reading from a 2+bar MAP sensor right?

I'm guessing the TSI is somewhere in between a stock computer and a FAST setup.(closer to the FAST than stock though)??

John - What about price, can you say anything about that yet?

Thanks for your input

John

 

How does the TSI unit know when to stop letting the pcm/maf handle fueling and start using its map? Is there a table of something for it where you can specify map pressure to activate it?

 

I think that it is referenced by TPS.

 

It is referenced either by TPS or Map(whether its internal 2 bar or external)what ever you choose as its ref.

John has already listed some features here's some more info about the TSI Box:

*Doesn't affect std knock sensors,closed loop fuel control
or idle speed control,therefore existing features of the
car are retained.

*Can control High or Low impedence injectors.

*Built in Turbo OVERBOOST fuel cut eliminator

*Ignition timing & fuel mapping are totally independent.

*Each Fuel,Ignition and stand alone map is made up of 17
load points every 500rpm up to 10,000rpm.Fuel flow can be
adjusted by -99% to +150%.Ignition can be advanced or
retarded by 50 degrees.

*Tuning can be performed on the fly(real time)and
permanently stored.

*Has on board Data logger.

*Can be used as an injector driver only or can be used as a
supplementry injector controller for up to 8 low impedence
injectors and still control ignition timing,boost and two
auxiliary outputs.

*Has internal Map 22.5psi.Can use 2 or 3 bar external Map

*Built in Launch control.

*Also has TWO auxiliary outputs which can control:
1)Nitrous(wet system) control.
2)Nitrous (dry system)control with additional fuel
mapping.
3)RPM activated solenoid control.
4)Gear change shift light.
5)Intercooler spray.
6)Extra fuel pump enable.
7)Generic output if above is not suitable.

*Has provision for a 0 to 5volt output analog signal to TSI
to log and monitor Air Fuel.

*Has an inbuilt Idle stabilizer which can help with large
cams to overcome an unstable idle due to large
fluctuations of the MAF or MAP Sensor.




I hope this helps to explain more about this TSI box.

 

***EDIT***

I read up a little on Speed Density systems and it seems they do take temperature into account since the density of the air is a function of temperature. The TSI box looks like it might be a nice unit if the $$$ is right....Any word on that PSJ?

 

How can i get in touch with someone about buying TSI?
