I've been doing some work for some friends developing different electrical bits to aid tuners. All of the work has been done for the high end import market but it would seem some of the items might be of use to you guys.

Can you please point me in the direction of tuners and vendors doing a good job with electrical and fuel injection related items? I am particularly interested in people that really seem to know their stuff on the technical side.

I know this is kind of a strange request but I would appreciate any help you can provide.

Thanks,
Bill

 

Some examples of what you are working could get you pointed in the right direction

 

The device currently consists of an 8 channel 5V input and 5V output and also supports CAN and K-Line communication.

The first application for the device was to alter ride height signals for Bosch suspension modules in mostly German and now some English cars. The ride height signal from each corner of the car goes into the module, an offset is calculated to either raise or lower the car, and then an output signal is generated for the suspension module to achieve that lowering or raising. The CAN capability was included to allow passive vehicle speed monitoring. As speed comes up, the offset is progressively removed to allow the car/truck to return to the stock ride height. The K-Line capability was added to allow for suspension manipulation in diagnostics mode along with diagnosing and clearing trouble codes.

I’ve attached a plot showing four wheel height sensor inputs, the CAN bus reported ride height per corner and the speed and speed offset values for one Bosch installation. http://www.lolachampcar.com/Misc.htmThe module is programmed by either a laptop or a simple CE device (like a GPS navigation unit). The laptop or CE device can also record data at five samples a second to allow the designers of a particular function to verify the installation.

A second application for the device was a factory twin turbo V-12 where the factory fuel control would open the waste gates at a certain boost level. This was a hard coded fail safe that could not be “mapped around” by reprogramming the ECU. There were four pressure sensors, one before the throttle and one after on each bank of the engine. The pressure sensor outputs were directed to the module with the module providing the matching signals going to the ECU. The pressure signals were passed though unmolested until the engine reached a certain boost level at which point the module gently “laid down” the reported pressure value to the ECU. This allowed the tuner to raise boost levels without triggering the waste gate open limp home mode.

With respect to other applications, there are many possible uses for these types of devices. One of my favorites is a CAN aware nitrous system whereby the device monitors throttle position, load, rpm and even traction control events to modulate a dry shot nitrous solenoid. Most modern MAF based cars will accept dry nitrous and properly adjust fuel based on lower inlet air temperature and increased mass airflow.

I would think there would be many more situations were control based on CAN knowledge would be helpful. I’d just like to have some conversations with tuners to see what they need.

 

Let me know when you devise a way to get a C6 automatic tran into a C5
the electronics are the hangup

 

I know nothing of the C6/C5 differences and would have to speak with someone who did understand them. I am finishing off a small project that handles some CAN traffic to allow a standard transmission in previous automatic installation. The engine compressor was not kicking on nor was the fuel control allowing anything more than a neutral rev limit without "seeing" the car in Drive. We just looked at some engine values and then provided a "Drive" message when appropriate. Perhaps the C6/C5 issues are that simple (although I would think not).

 

I'm told they are not simple
If you could figure it out, many would jump at the solution

 

Check with RPM Transmissions. They have installed a couple of the A6 transmissions into high Hp C6 Z06s. It isn't an easy task at all and takes a lot of work.

Or you can get a TCM from a A6 car and do all the required wiring to make it work. I don't think it would be that hard to do.
