need help --calling electronic whizz-kids.Got itb's and ecu - now i need to connect up but it's not that simple.got 30 amp fuse,four point relay and damn module which is not required.Now the inj takes 5v power--does the comp/ecu send the message or do u have to bring the volts down. WHY because i'm using bike t/b--according to hyper racing in usa it is 5v.the gotech ecu manual shows 3v and no module with hall type dist.ANY help will do

#OOPS#, sounds like a jumbled mess! what type of ecu is it? that pretty much determines everything!

often with many ECU you have to use "dropping resistors" to reduce the voltage to the injectors

But with other ECU, it's built in to supply 5V.

Most auto sensors etc. run at 5V, normally the ECU will supply regulated 5V but it will depend on the total current it can supply.

Check the installation manual for the ECU, it should explain all you need..

the ecu is a gotech mini x.--Sorry i know it seems a mess but it's not so bad.i just wrote in short. the pinouts are there but this is for std setup not bike t/b.the only problem is the voltage.dont want to #oops# it before it's started.read all the warnings about the EMI,only one wire on thermo,relay,fuses etc etc. they dont take into account that some datsun owner will do it differently.anyway got a auto elec --he says he has to get info on tps wiring and voltages etc so lets see.thanks was hoping some bright spark has already done it. always better to look and learn
