Urs Gretener, owner of GPE, have upgraded his race car(a very nicely done

race car as you can tell), and also put new engine management system in it,

which we got a call from him to do a full wiring job for it.

After we went to Urs's shop, we took all the meassurement of the car. We

started to build the engine harness and this switch panel, which Urs made a

very nice plate for it(water jet cutter baby!)

Then we filled the swtich panel plate with all the high end circult breakers and

switches. All of them are mil spec quality which is highly recommended in a

race car like this. Afterall, electrical problem is the last thing you want in a race.

Here was Greg installing the engine loom onto the engine while it was out.

We planned the length prefectly, so it sit on the engine beautfully.

While Greg was installing the engine loom, his assistant Frank was installing

the chassis loom and also wired up an Aim MXL dash and data log system in

the car.

Here is the finish look on the engine. Everything was routed and installed firmly

on the engine, with the disconnectable mil spec connector, the engine can

be taken out fast and easy without disconnecting every single plug on the engine,

it also reduced the chance of human error of plugging in the wrong plug into

wrong sensor.

After everything was set and done, Urs took the car out to Willow Spring

raceway to test it out. Greg was checking out the data and diag. screen of

Motec M48 program to ensure everything is on the right page.

After that, Urs took the car out and test drove it on the track. He was pleased

by the engine power and respone gain from using a Motec engine management

system.

Here is a final shot of the cockpit of the car. Everything is installed nicely

and minimal wire is exposed to see which created a very "clean" look.

Here is a close up for the switch panel which we like the most because of its

easy to read and reach.
