Haltech E11V2. Does Map Sensor Get Power From Ecu Or Battery

[joe blo]

hi mates im just thinking about my haltech that stopped working in my rb20 hilux. does the map sensor get power from the ecu or somewhere else? its a external 3 bar haltech one.

im trying to determine how dead the ecu is before I send it to haltech. it has around 5 volts at the map sensor wires.

ecu does nothing else in regards to spark or injector pulse

I haven't got a cable to hook up to laptop to see if anything is happening im hoping I can get the tune out of it once I get a cord or take car to the shop then send ecu away to be repaired.

does anyone on Brisbane northside have a laptop cable I can borrow sometime?

[Ben C34]

It would get the 5v from the ecu.

laptop cable is just a 9 pin rs232.

though you will probably need a serial to usb adapter

honestly i'd bite the bullet and just ditch the E11v2, they are so old these days and completly junk. Even going back to a nistune would be lightyears ahead

[Blackkers]

If you send it to haltech they will almost certainly be able to save the tune. 99% sure

I had a flood damaged honda Ecu, the hondata annex board was f**ked too but we still pulled the tune off it.

As for what Simon said, you could get a nistuned RB20 Ecu for very cheap these days. But then you'd have to install an AFM..

yea thought about nistune if I cant use same tune and repair ecu for around 400
