Rev3 ECU swap progress......

[Murf]

It does but i'll tidy it up once ive gotten rid of the error code related to the O2 sensor heater. :)

Looks just like a spiderweb when a spider is on weed.:) Good man!

Hi paul

Thanks for e-mail

What you need to do is put a 8k resistor across the pins B+ and ht1

You can do this easy enough right at the ecu with small bit of wire, just make sure is all shrink wrap or protected after.

You will no longer get the heater o2 sensor error code

Good work on conversion tho :thumbsup:

[Murf]

Cheers dude!
I got the HT1 bit but i didnt know if it needed grounded or a feed to it!
I'll pop ouyt and try it now :)

[adamh]

good job murf, shorty you on the waccy? lol

did you use the standard rev1 loom for that conversion murf?

[**BETSY**]

Murf- Error codes gone now?

[Murf]

Yep, the error code for the o2 sensor is gone now but i only used 0.6w resistors and they burned out, dammit! going to get some higher capacity ones and try again!
The one for the engine lid temp sensor is still there and will be until i fit a temp sensor to the inputs.

Adam, Turns out my car has a rev2 engine and loom, not rev1, so the swap was easier than for a rev1 car.

Rev3 or ST205

Ignitor (£50-70)

Map sensor (£70-90)

Mat Sensor (gtschris sells them) (Around £50)

4 Wire O2 sensor

Fuel pressure Regualtor

540cc injectors



Ok now you don’t need the rev3 4 wire o2 sensor as you can fool the ecu by the use of a resistor. The extra 2 wires on the rev3 are used for heating up the sensor for better readings at idle but you can just put a 8 Kohm resistor across the 2 wires and everything is cool



Now if you are not going to be using a powerfc then I would say get the rev3 FPR regulator as the fuel pressure on a rev2 regulator is higher so would make the your car run abit rich but if you are getting a powerfc then no need as the powerfc can control the fuelling to lean out mixture.



The Ignitor plugs straight in to the rev2 loom but you need to take one plastic edge off to allow to push in, your see what I mean when you go to plug it in.



The map sensor just plugs straight into the rev2 loom also all wiring is same.

Some Rev 3 swap pointers!

Another major thing is to check the static ignition timing, mine was too far advanced and caused all sorts of problems that were hiden by the rev2 ecu setup and became a problem when i swapped to the rev3 system!!!
