    Performance Chips Revisited

    Hi All
    Anyone had experience with Innovative Performance Chips out of the USA?
    Read as many threads as i could find on the forum but didn't come across these.

    I have one and based on what they are claiming it is a very cost effective mod to gain some economy with some bonus HP. They break into the MAF sensor circuit with two snazzy little clamps that you plug the black box into. It's for a D2 V8.

    Can anyone tell me which of the wires in the attached pic are the MAF wires please - from what I can gather only 2 are the MAF the other three not sure?

    Many thanks in advance.
    Cheers

    The 2 wires connectd to the MAF are as follows: the red wire is the 5V input to MAF from the ECU and the MAF output is the blue/green wire, the brown/pink is the 12V supply for both MAF and IAT sensors contained in that casing ... though i strongly recommend to not go for such "tuning" to alter the MAF input with some tricking device cos even if you'll gain power the whole engine managmenet will be mixed up... these so called "performance chips" were invented to tune CAN-BUS vehicles as they work with digital signals which the D2 is not, or it's a simple voltage divider which is even worst ... how ever it is modifying sensor inputs is not the correct way for power tuning ... those who are selling these things dont care that your engine can suffer due to high EGT in time

    Thanks for the heads up guys.
    Won't be going there with the 'tricking' chip.
    Appreciate the quick response.
    Cheers

    Long time ago when i knew too little about these things i bought a tuning box for my Td5 which was advertised to reduce consumption and increase power(not cheap one), after i fitted it i was very happy cos it made a noticeable difference in throttle response and power(can't say nothing about consumption), i didnt have EGT gauge at that time, i can't prove it without doubt that it was because of that tuning box or for some other reason but after about 10K km of happy driving i had to replace the head as it cracked on the exhaust side and after 2 injectors were diagnosed to be bad i replaced all 5 of them(with new) then i replaced the turbocharger too cos it was worn.... then i got rid of that marvelous device and fitted EGT + ECT gauges and started to learn about how the engine management works... end of story
