right i'm off to tony's tomorrow morning to have a look at this ego problem, and to fit the diode.

Tony's said about reflashing the ecu. do you have the files tony???

also any pointers on the ego thing wiring wise and setting wise?

Right, not reflashed the ecu as we want to make sure the config file is right first,
David or anyone not sure if you can see a problem within it,

on another note:
added the diode today and fired the ole gal up on the new 440cc injectors,
man she does arf rev a lot quicker and crisper now.

just need to sort a few things out so i can run you a datalog off Dave,
the injector openings etc can't be changed until you have looked at the datalog yeah Dave?

What firmware version are you running?  I'll see if this can be replicated.  It might point towards an answer for you both.

Just looking through published configs and it seems that Tony has:
ego_conf=06

and most of the published ones have:
ego_conf=07

Which is the only significance that I can see.

It could be the thing causing the problem, and wont hurt to try it.

no worries mate.
i.ll do that later this week,
why do you have to use generate mate???
cant you just edit the downloaded config, save it then use the upload-config bat? to upload it back to the ecu?

The config is designed to be close to human editable as possible, but to upload it to the unit it needs to be made VEMS readable which is what the generate-config does, it turns the likes of:
primep=00
primep_temp_scaling=00
cwl=28
cwh=14
cranking_thres=03
awev=41
awev_temp_scaling=0F
awec=C0
