should be about .5-.7v at 0% and then goes up to 5v at 100%

As I'm using this engine in open loop with no O2 sensor hooked up, do I need to turn off the O2 sensor in the bin? The car doesn't have an engine light so it's not a problem, but can it upset the way in which the ecu works? Is there a need for the IAC to be connected?

Here is a log from several months ago with the naturally aspirated methanol chip, it was a run in 4th gear. As you can see it could do with some more timing, as the egt could be higher & the afr could be richer when the throttle was opened up.

if you are just running no o2 sensor and an unmodded tune it will run shithouse it dumps in heaps of extra fuel to keep it safe .

I fired the car up with a chip with the std fuel & spark maps as suggested by Holden202. It appears to a little lean everywhere so I've upped the ve 10%. I noticed in the bin that there is a "Boost VE & Boost main Spark Advance" tables, does this mean that if I fill these tables & empty the std table, that I I can use this with the blower connected?

boost VE and boost main spark is the extra half of the 2bar from 100kpa too 200 kpa so the boost area still need the other tables for off boost

If its lean everywhere, keep the stock VE table and adjust the injector rate - thats the fudged figure at the moment. Get it running ok and then fine tune using the VE table afterwards.

VL400 The injector rate is set Map A=.06 Map B=.03. Any ideas what to change it to, bearing in mind this is methanol?

If it needed 10% more VE to run well just add 10% to the injector rate.
