Hi everyone my bro has just bought a new engine management for his s2 so we can learn ourselves to mapp i know it could end up badly but we just thought we would jump in at the deepend otherwise we would never learn so, we have got it all wired up now and got a base map so we have the car started now and the car was running rich at idle so we started to pull some fuel out and got it from 9-10 afr to around 13 afr but when we try to pull a bit more fuel out (to try and get it close to 14) its seems like its going to cut out.
Any hints or tips would be nice as i say its our first time we have done this.

 

I wouldnt worry too much about idle AFR, its such tiny volumes of fuel and air anyway that the mixture really isnt critical.

 

Thanks for the reply chip i have been studying your mapping article that you wrote in the total vauxhall mag its good really intresting.

I wasnt sure if the afr guage that i have was reading correctly its a innovate lm2 and have only used it once before so it should be.

 

Just thought id let people know its haltech engine management on a 2.1 zvh with t38

 

Mine idles when warm at about 13.8 so your not far out mate, doesnt like being any leaner, also depends what cam you are running.

 

Aright karlos it just got a piper t2 for now also my based map is based off a focus rs.

 

T38 fook me do u a swap for a t34 if u want

 

Ha Ha no thanks
