Hi.
I'm trying to find out how to fix a wiring problem i have with a tune it chip I have recently bought.. the instructions say thAt I must wire two wires to the fuel pump .
1 to the fuel signal wire
2 must be earthed to the pump.
My problem is I don't know which is the signal wire on the pump. I thought it was the red wire on the spill valve but the chip didn't work at all .
I managed to find the fuel wire on the ecu and I cut into it and joined up the chip which made the chip work but not very well..
How the chip performed was . There was no extra power untill 3800 revs and then it took off like a scalded cat . I can only presume that the power delay was because the signal had to much resistance while it was wired to the ecu .
There is no way I want a burst of power at those high revs .
It's unfortunate that the tunit instructions are basic and thAt they don't match my wires or that tunit it themselves has made any effort to help me out after 50 calls at least .. please can some one tell me what wire is the fuel signal wire on a 1kzte denso pump.
