ok can anyone please help and tell me what these figures are for a 2.1 zetec turbo engine as someones making me a map but i dont know figurs below


its a 2.1 zetec turbo, the engine was a 2.0 mondeo



3) Factory timing settings for Idle , max advance ?

4) Stock and/or esitmated idle speed ?

5) Stock idle vacuum (manifold pressure) ?

6) Max boost you think you will really ever have. Really.??

reality

What a scary concept.. maps by post!! Anyway.. here goes..


You really want to go for say the stock ford table in the vacuum area.. idle around 5-6 deg.. max advance where?

~850 rpm


~30-40 kpa

Only you will know the answer to this.. 1.3 bar with the right turbo will see you 300bhp..

i gather its ignition max advance mate

reality

At what load site though? 40 degrees is about the most you'd see anywhere on the table

rsguy

not sure on the load site mate, any ideas what figure reality
??


also for around 240 bhp what psi ?

heres my current spark table

hmm..
This is a dodgy topic with a lot of well suspect questions on it.

The answers are all TOTALLY dependant on compression/head ports/cam aggression and timing and the above figures may either:

1) Be fine.
2) Not even idle
3)Destroy your engine if you interpret the advance answer wrong.

Take care. get it done PROPERLY.

Ginge !

and i think stu has a slot this weekend

.. unfortunately that's a million miles out from where it needs to be (on the positive pressure side).. as Stu says, you really want to get someone with at least some tuning knowledge to get this remotely correct.. the vacuum part of the table is acceptable, but it's also relatively hard to break stuff in this area.. boost side is another story..

I would also space the map very differently from the start. Half your breakpoints are now above 5000rpm and they are not very useful there. And what's this with zeroing everything above 150kpa?
