480 turbo ignition

ive now got my engine running on my vems ecu which is very similare to the megasquirt but i need to know what ignition timing to put it does anyone know cheers

where on the map do you need help? You could get on vems website and find a startup map that suits your application and take it from there. Undar load its all up to your boost but prolly 28 degrees at 1,5-1,7 bar.

Btw how much did you pay for your management?

i payed less than£300 for the ecu and loom it was used and off a friend

im running bigger injectors and turbo so will be running abit more boost than standard so dont want to get the advanced wrong as cause major damage

Good price m8,

I understand your concern, i would defenetly go for the coil on plugs option in your management for much approved ignition control. And a good "beginner" tip is to map on 95 to its limit and drive on 98 to be safe. And when you get more into it you can opt for either octane and optimise your map. 1,5 bar will put you in the 230 hp´s on 98, if you get your fuel and ignition right, offcourse cooling, turbo, dp must be right, and you prolly should fab a better inlet and exhaust manifold if you want more and smoother power. I would go for 28 degrees at 1,5 boost to start with. But if you have a vems, why not put in an b4194t engine? Thats easy 300 hp. 500 hp with rods.

what engine code is that from mate ive got a guy doing the mapping for me who knows what hes on about unlike me lol when it comes to mapping the engine il try it with 28degress of advance with the boost pressure youve mentioned then get him to get his knock equipement on it ive yet to connect my wideband but m guessing this will also help alot with if im over fueling alot

thats from an volvo s/v 40 T4. your fuel should be at 11.8 af/r with those light cars. I wouldent go leaner than that.
