On the Secondary table? I don't use that table at all and have disabled it.

Double check that the switch isn't activating something else too - especially the secondary map (under parameters).

I just noticed that the switch also activates the secondary table. Hopefully all solved now.

I just wanted to add - in the log the AC switch is activated to high at 3:18. The 'cut/jump' can be seen at 3:24.

Hi guys,

trying to set up the boost by gear low/high tables. Have a switch wired up to the A/C which works fine.

Low boost table works fine - no issues. But with the high boost table i get a weird cut out no matter what i set it too.

Tested and tuned right up to 70% duty & at 70% fixed duty i don ...

Thanks Spunkster - I'll try it. :)

Should the ELD be on or off? Which would give the most consistent voltage?

Ok cool, so i just lift the S300 board from the socket/ecu and mail it to you?

Do you have a UK vendor that I can mail the old one too or is it international mail to you only?

I just wanted to add i wired up the Pump direct to the battery - this helped with the indicator ticking but i'm still getting a pretty big AFR drop under load (mainly lights and rear de-mist).

ELD is disabled, should it be enabled or does it sound like another issue?

Hi Guys,

Hoping someone can help as i'm stumped (again).

Getting quite a large AFR change as i turn on the lights, interior blower, stereo & rear screen demister. As i add load to the system the mixture leans out going from 12:1 right down to 15:1 roughly.

I've added the dead times supplied by ...

Liking the look of this - just wondering will the PWM components be affected?

Are you upgrading the ECU's we send in (removing old board and adding new)?

Just wanted to follow this up, it's def not the Hondata, Solenoid or Wastegate causing the issue.

The car won't make more than 9 PSI even with the Wastegate constantly shut.

Examining turbo and internal Wastegate leak. Also blockages.

Thanks for everyone's help and suggestions. Once sorted I ...

Wow that's really weird. First triple check your lines and the wastegate diaphram. A 7 psi spring should be able to hold to at least 20 psi (maybe trailing off in higher rpm). If everything looks good I would try messing with the boost by gear tables before going to a larger spring.

Do you mean ...

Gave what you suggested a go - sadly no improvement. If anything I seem to get the most boost around the 31 - 32 hz range using the MAC valve, going in either direction seem to reduce it.

Any other thoughts?

Would really like to avoid having a mega spring in there if i can. :(

Yes, increase the variable frequency. But do it slowly, 1 or 2 % at a time. I increased it 10% when I was messing around and went right to boost cut lol.

And that fixed at 80% is quite high. Mine was at 42% but I've been using BBG so long I don't remember what psi that was giving me.

Cool i'll ...

Try setting activation pressure to 1 psi

Previously the early activation seemed to make it worse - but i'll try it again. :)

Which ECU are you using and does it have the boost components installed

I'm using an S300 - unsure of any further version details but i can find out if needed?
Yes PWM ...
