Jorgen.
I understand Rob has talked to you regarding the possible split inductor in my vems,:
would this cause the said spikes we are seeing?
and/or what else would it upset within the ecu,
it's being sent back to Rob this week, but curious to find out what it would upset within the ecu.

 ;D ;D ive got ego ive got ego ive got ego  ;D  ;D

not sure if you are aware rob the ego is working mate  ;) ;D :D

in the lambda control mate the rich and lean settings,(10% your settings) is that how high or low the lambda will go before the ecu does correction?

just has a quick peep at the settings mate,
did you reset my temp table? as im using the rover temp switch mate,
and dont look like what i thought they were before the ecu was sent away mate.

and in settings->EGO(lambda) control:
ego nbo2 connected is set to disable
ego nbo2 pid config is set to enabled
does that matter?

EDITED>>>>>
and the datalog to go with tonights start up,

Didnt touch those temp settings as far as I can remember.

As for the NBO2 section - if its disabled the other setting is ignored.

They are to limit the maximum % of adjustment.  The idea is that you should be within 10% of the target mapping by hand (in reality you should be within 2% to 5%).

cheers mate,
once the throttle cable arrives i'll take her for a run and do a log to see how she is setup wise on the VE and pop it on here,
cheers for your help Rob,
next will be ignition mate :D

Cable arrived,
took for a run, still have them spikes now and then so need to look into that a bit more,
Rob, could the tach output on the cdi be playing up?
can i connect to the -neg side the coil instead of the cdi box to see if we still get any spikes?
or wont it work with my settings?

here is todays datalog along with .msq
www.v-8.org.uk/zipfiles/log04_04_08.zip

now can some one help with tuning the lambda readings now please, :D :D
any one got a program for this?
i did kangaroo while on light throttle and i think the engine actual lambda went real lean, think it was 4% throt around 2kish rpm towards end log

and forgot to say the car ran defo smoother Rob,
so the repairs have done some good mate, thanks.  ;)

I wouldn't connect anything to the side thats driven by the CDi, its likely to kick out huge voltages.

Theres no substitute for getting the fuel mapped properly, EGO will only do so much.
