Title: 1.8T me7.5 tuning boxes?
Post by: RTechUK on 14 September 2011, 08:38

Has anyone come across a tuning box for the 1.8T DBW ecus?  Over the last 2 months I have had a Skoda VRS ex police car and a Golf AUM which both had small adjustable tuning boxes fitted to them?  We only started to look for issues when both cars failed to make power and going by the logs we notices something else was in control of the N75 valve and not the ecu.  It seem like the box splices between the N75 feed and the injector feed on the loom plug on the ecu?
 Switched on with a stock map it made around 20bhp 20lbft gain as the throttle valve was limimting the power,  On the AUM with the an R-Tech spec1  and switched off it would only make  180bhp/180lbft, and the adjuster fully turned up 213bhp 238lbft.

I would would like make one of these boxes up as I would save no end of time when custom mapping as the N75dc can be set up on the fly, then that infomation can be later added to the map.

I will try and get some picture posted up?

Not cheap for the multi channel unit..I only want to control the N75DC% and have some kind of reading based on PWM v RMP to give a real time N75 reading on a LCD display.  I will look on to making one up maplins here I come.

sounds like your only after a basic PWM controller.

i has a littel program on the workshop laptop that i found somewhere on the net the uses the soundcard to create a programable PWM controller neeeds a bit of amplifaction but can be quite usefull
