Lean tip-in?
Hi, does this look like typical "lean tip-in" to you guys?
when I step on the gas there is a very brief lean spike, occsionally I can feel this when driving, although the car has covered several hundred miles and is running well otherwise.
I've tried adding fuel in the injection map, and this has helped somewhat, but the lean spike is still there.
I take it the acceleration enrichment map won't work on my 1992 1.6?
Also, would adjustig the airflow map help at all?
Just looking for some ideas, I plan to possibly get an O2 clamp fitted soon, would this help with the lean spike?

cool, I like a quick reply!
I can source an O2 clamp over here in the UK, I'll get onto that tomorrow.
ok, in your opinion, would this lean spike be having a detrimental effect upon the engine?
I'm a little concerned about it, but so far have not had any problems.

And other than the hesitation, you should not have a problem unless you hold it right at that point.

Olderguy, it just so happens that I have bought one of your O2 clamps off a guy here in the UK who bought it last year but then fitted Megasquirt and so never actually fitted the O2 clamp
I take it I can safely put the pressure sensor in line with the MAP sensor? (which lives next to the EMB and stock ECU).
