have you adjusted the 0v and 5v wideband settings in the tune to match what the wideband analogue output is set to ?

I'm pretty sure it's the innovate Mtx-l and I'm not using an 808 I'm using a vs manual pcm so don't think I can do the pull up resister mod

well that's where i'd be starting first then.

for example innovate normally has the analogue outputs in the range:

0v = 7.35
5v = 22.39

so in tunerpro find the settings for wideband 0v and 5v and make sure they are set to that.... also connect up to your wideband controller and confirm that the analogue output settings are infact those numbers.

also if your using it through a 424 pcm you might need to remove the resistor off the pcm to get the reading to work right, theres info for that in the $11P doco I believe.

If it's a VS manual as in a 082 or 305 you can do the resistor mod. Not essential but removes some error and makes setting the scalers easier.

Yeah it's the 305 running 12p. But the picture on here that shows you what resister to remove is on an 808. Looks totally different.

Think I've found my issue. I've connected the vac line up the wrong way around on the wastegate

Also that lean spike is no where near as bad but still is there. If notice the injector bpw is dropping down near 1ms when it happens and these injectors are rated at a minimum of 1ms so I'd say I need to set the single fire. Time to set up another bin and start from scratch I think.
