MSGR_PHOTO_FOR_UPLOAD_1523014164079.jpg_ got a few holes in the bonnet now

I know how you feel I had to cut more holes in the bonnet to fit ST170, exhaust over the side and not through side panel and PX600 air filter for twin 45s. Looking good maybe next winters project....whats another hole in the bonnet.

Do you know what your Air Fuel Ratios will be?

Have you got a wide band o2 senser?

Yes got a wideband getting a steady 14.5 at idle and reving to 3500rpm it drops to 12 but this is just reving it on the driveway have yet to do a data log rain has stopped play

When you try it under load see if it gets to around 11, much more than that and youll be into bore wash territory.

 

Can you set a target AFR?

Im assuming you have capability for closed loop self learning?

 

Id target lamda for cruise and no more than 10.5-1 under boost.

If lamda is a little lean try 13.5.
