if you have a laptop you can buy an innovate wideband kit and it will come with everything you need to log the afr's

wide band
- innovate have a had a lot of software problems
even when i contacted there retailers about aquiring one they said they have them but you will need to sflash the memory and upgrade them yourself as they keep going wrong

i bought a Zeitronix
i think its personally a better unit and does a lot more - and u can log rpm straigh away without buying another adapter for £80

if u want to see a screen dump look for my car for sale in the forsale section
afr should be 14.7 : 1

(just a note i bought a boost solnoid as well thats why i map'd boost vs rpm vs afr )

check the wideband forums lots of knowledge there but bear in mind all in gona cost easy £300-£400 - how much is a rolling road session ? £40?

my friends works very good with the datalogger and innovate, also it comes as a kit.. doesn't need to buy anything else for 80...

dude sod that its an expensive way to do it, just hop on the car ferry to pompey and go to the rr there bud, iv heard good things about them and monka paid only £60 for an hour on the rr when he got his blitz ecu, makes more sense :)

mate its a "self learning" ecu so you plug it in and it should adjust within a certian amount to compensate for the mods to the car, the blitz and sard ecu's do the same so in effect just plug it in and drive about for a bit and it should acount for the air fuel intake and self adjust, you only realy need the rr session just to be sure that the fueling is ok and not too lean/rich from what i remember monka's blitz ecu was spot on with the fueling and all he did was fit it and drive to the rr in pompey :)
