Motec System Question's

[ish]

Hi i just have a few questions to ask to help me understand a few things better.

Any comments or better still links would be fantastic.

What is the general process with Tuning using Wideband lambda and logging feature's for Road/Track Tuning.

How do they piggyback the M8 to the standard GTR Ecu so that functions Like Attesa, Air con Etc. are run perfectly by the stock Ecu.

This is basicly the setup i have designed and wanting to use so i can learn to tune the car my self on the road & track days.

Thank's

Its pretty much a case of sharing some sensors with the factory ECU basically the only sensor you want to share is the crank reference. I'm not actually sure on the trigger setup involved with a motec on a skyline but you might have to make an external trigger setup - 12 even is usually what alot of people use. That way the the motec can now take control of the timing. Then all that is needed is to patch in over the top of the injectors with the motec, make sure the impedance across the standard injectors is the same as the standard inj by using resistor. Make sure also that you use a separate ECT sensor and if possible another TPS because if you share them the internal impedances between the factory ECU and the Motec will be different which will mean you will have floating voltages and your TPS will never be set right.

Ah thanks rob ! You answered my next question already about individual ECT and TPS sharing problems.

I am trying to find a good EFi course to fill in my gap's.

Cheer's ish!

You don’t need the standard ECU, the Motec handles it all.

I originally was planning to do that SydneyKid until Motec themselves (Mark McCoy Motec Support) recommended the piggybacking System.

LOL

Maybe he was looking at it from a budget point of view? Have to see what some of the installers say in Melbourne...

I can put up the Mail if anyone is interested?

you should try talking to the whites, they've put motecs in all their race cars, and their road GTR.

info from the motec site.
