MG ZR: Cams & Maps

[lolsteve]

how does this one pull compared to the blue one?

Pulls well despite having being effectively stock whereas bluey had janspeed manifold and a fresh headgasket 
This apparently has 5hp more at the wheels with the stock map

You'll not see the puffs of smoke when on the move, they are only small.

12.5 at full load, with timing advance, in my opinion, is too lean. Needs more fuel.

£5 says you'll hole a piston in the next 6 months

Well it was 12:5 at not quite peak rpm so probably got richer. Do we think an additional 0.5ms of pulse width would sort it back out ( 5% increase at WOT). Sadlly can't exactly do live adjustments so would have to make educated guesses
