Urgent help please! Ignition maps
blakep82 - 27/5/21 at 09:54 PM

I've got a track day on Saturday, and my ignition timing is well out, I think
Power is poor, exhaust pops at all Tom's, are gauge shows mega rich but jets are a bit too small. I think it needs to be advanced a fair bit

Can anyone show me any ignition maps for a 2.0 16v n/a engine please?
vauxhall x20xev, Carbs are dcoe, 145 main, 175 air corrector, F2 emulsion, 60F6 idle, 36 choke, 4.5 aux

It's very lean at idle, and very rich on power. Makes a miserable 115bjp at the moment.
Hopefully someone can give me a few tables to get a starting point from

Thanks!

When you say maps I think you mean fuel injection. As I think you have carbs have you tried this site?

I would be a bit wary of having a car on a track day without the engine set up properly, it could end up a very expensive day. Spend some money on a rolling roar set up, you then will know that it is running spot on.

Mm agreed, tootling to the shops on a dodgy map is OK. Track days are another thing. I guess that's why he's asking for a decent map

Just re-read the request. It is actually for an ignition map not the carbs as it's mistakenly thought.

Have your looked on the megajolt forums?

Also agree with others you're risking a big bang and creating an air-cooled engine or something equally expensive
