Another thing I just noticed. With the fuel pressure regulator the guage stays steady at idle and slowly increases if I slowly increase throttle. But if I give it a good rev the fuel pressure is pretty much all over the place, doesn't know what it's doing

The logged injector BPW is the required fuel amount in the pulse, the actual pulse width to the injector is opening time + BPW. But with large injectors its important to get the single and double fire setup properly.

More vacuum should be lower fuel pressure, higher load/MAP a higher fuel pressure. Giving it a rev will make the fuel pressure vary a bit and would be hard to correlate to MAP.

Also in the log you posted sometime back in this thread, DE is still active and is likely your lean spike on closing the throttle - its not a bad thing. Watch the item in thhhe log "Decel Enleanment Applied to BPW".

Change the item in your bin "Decel Enleanment Param - DE delta throttle angle threshold" to 0.02 and it will stop DE kicking in so much at cruise (as the TPS flickers between values).

Make sure the option flag "Map x: set=Update Baro During Run, clear=Only Update Baro When Engine Off" is clear. Your baro is maxed out.

It likes to idle around 50kpa at around 26deg of timing. I'll set the single fire like I think the way you suggested 2.0 an 2.2. I'll have to look into why the update during run isn't working. I untucked that and ticked the ve multiplayer one

Update Baro during run should be unticked and Ve multiplier table for baro adjustment ticked is how I've been setting it up

it was the msd 2 bar map sensor that wasn't working. I changed it to a new wells 2 bar map sensor and it's now reading like it should

Good find on the map sensor. No hope of anything good with a dud.

You may find it likes less timing at idle now. Are you targeting idle timing to where it pulls the most vac or close to?

Yeah it seems to like 26deg at idle I'll get 50kpa but if I put more timing into it, it doesn't do anything until I get upto around 29deg. So I've just set it at 26
