Just had the saff MOT'd. Bloke doesn't normally bother checking the CO,but i got it checked anyway out of curiosity. Running a stg.1 Bayjoo chip,Pipercross and 'goose exhaust. This is what i got:
Idle 1.6
2000 rpm 2.8 ish
3000 rpm 6.2 ish
Now is it so high at 3000 cos it should be starting to boost (but isn't cos it's in neutral) or am i burning a lot of Optimax for nothing??
Advice please!


(cunningly edited to attract attention)

 

its not done RPM related... the MAP input is used to work out boost...

ie the car should fuel perfect at 1psi all thru rev range and also fuel perfect at 30psi all thru rev range with no alterations

altho im sure i just explain thats REALLY badly

 

Anyone?

 

i tho the more revs the more fule?

 

So did i,but should that increase the CO that much?

 

No, as std, (same basic fuel map as a stage 1) a cossie will run at around 0.5%CO at the rpms you mentioned when revved in neutral.

I run my own stage 1's at around 2% CO cruise but thats personal choice.

6% is a tad rich and wont be helping your fuel economy when driving at very light throttle.

 

fpmsl, good map

 

Karl he asked for Stu If he wanted someone who calls ME IMA Racing a sick twisted person..it would have said "FAO that goon that called IMA Racing a sicko"

 

Sounds more like excessive fuel pressure than a bad map to me initially.....

 

so at 3000 what i expect to see on mine??????

in neutral

 

A BIG cloud of Black Smoke.

 

thats sooooooooooooooooooooooooo true

 

mines got a fair bit of black smoke at idle, i de catted it last night and fitted a ST170 4-2-1, is that why???

or is my power boost valve set too high????

 

Thanks fellas. So,i am just wasting fuel or am i going to create long term problems(bore wash etc)?
If the fuel pressure IS too high does that mean my regulator is poorly or something else?
It's running yellows( )by the way! Have got no problems with the performance tho.
Any further advice appreciated
