I know that this is a tecchie question in the projects forum.....
are anyof you suffering from any problems becauseI have just blown my third ECU !!

Z Cars check everything out last week and couldn't find anything.and re-did the wiring loom..if it wasn't for my cutoff switch I wouldn't have a car as the wiring loom sarted to spark and smolder and the ECU got redhot and the cockpit filled with smoke !!

Are any of you using a different management system or have you made a complete new loom ?

Responses would be greatly appreciated as my sense of humour has had a major dent as well as my bank balance and I would like to complete a journey without being trailered home (I could have bought a TVR and a tow truck ).

Cheers guys

PS the car is the dogs danglies when it does run !

is your r1 injected, did you make the loom and what year is the engine? if you saw sparks and the harness has melted try unpicking the insulation and tell me what colour the wire that is most toasted.

i have three lives ignition injectors ecu they all have separate fuses so if i get probs and a blown fuse i can tell witch circuit it is at fault

also if the bike had a yamaha alarm there is a horible little black wire with is actualy a live

It may not be the wiring loom, it could be the generator over charging and frying the ecu if it has done it on another loom then the problem may lie elsewhere in the car but the loom is carrying the load to the fault???

Im just finishing my loom off now but cant really offer any advice as im not familiar with the R1 setup but keep us posted.

Cheers

thanks for the replies....
2002 injection

I've had 3 different problems now:........
Day 2 of running..........misfire under load...a friend traced with a meter back to ECU where the resistance was high...got a new ECU and did 100 miles with no probs.


3 weeks ago on my way to first track day just finishing overtaking a line of traffic and no power....managed to get back in and turn off road without causing any embarrassment...blown fuse at the solenoid and blown ECU.

Managed to get another ECU ...picked up car from Z Cars on Friday...they have checked everything and "re-did" the wiring loom..trailered it home...3 miles yesterday and melt down !!

I will look at the loom once I have spoken to Chris on Tuesday.
The loom was modified by Chris in the first instance.

I have a Digidash so can see the charge going through which seems normal

cheers John

hi john 2002 injector or na and did you take the feed for the rev counter from the injectors or one of the coils ?

i have seen this happen before on a bike an early r1 it had bin down the road on its left hand side and damaged the flywheel cover, the cover was replaced and other repairs few weeks later it blew a fuse then another one.
one of the ones on the starter relay.

eventualy he put a larger fuse in and hey presto the ecu started smoking turnd out to be a short behind the caseing on the fly wheel.

on later r1s the voltage reg is on its own circuit where as the early ones had 2 voltage regs inside the ecu on inspection of his old ecu (cut open) the tracks and both regs were burnt to a crisp

if you can tell me what wire or pin out the ecu your mate looked at it will help i have all wireing diags us eu uk
for the r1 on my pc

or ask here R1-Forum.Com - ignition/ tci problem

Hi Koss
many thanks for the info....you are giving me some excellent help.

the feed for the digidash is now from one of the injectors...originally taken from a coil but the revcounter didn't work...

..after the starter solenoid blew on the 2nd time a larger fuse was put in...hence the meltdown of the ECU....

Atleast we can start looking in a different direction now

I don't have any spare time for the moment but will try to get some help in looking into this...will let you know the outcome .

many thanks John

Good luck with the problem, But i dont envy you trying to find it as R1 ecu's cant be cheap to buy at the rate you are going through them??

john have you got any old ecu s try and take one to bits they can reveal quite alot and dont!!!!!!!!!!!!!!!!! plug your new one in yet. ive just had a look at my harness and there similar as mine is 2003 the starter relay wires are tricky and you dont wire them as they were on the bike. also the fuel pump must be powered independant you will have no relay box now and the ecu should only be there to modulate signals and not feed high amperage things like coils fuel pumps i know it may seem a mine field but the rule is to make the ecu do very light work. if you want a pdf of your harness pm me

the website is now letting me in atlast

Hi Mark,
I got hold of Chris on Tuesday and am getting a new loom to try again....managed to get hold of another ECU so am waiting for that to arrive .
I'm away for a few days so have shut the Mini in the trailer and will attempt to try again with some help I hope as I am not confident myself...will be following Koss' advice and will let you know the outcome



cheers John
