I'm building a 2,4liter cossi engine at the moment (will post some pics when it's done...) and one of my biggest problems at the moment is the ignition map (i'm running an electromotive tec3 standalone ecu with 8injectors, wastet spark...)
the last map was from http://www.rplab.co.yu/downloads.htm
(it's a map for greens, and 330bhp or so)

engine specs:
2,4liter (88mm stroke 92mm bore, 130mm rods, 32mm comp high) turbolar exhaust mainifold, throttle bodies (4*50mm) 8 injectors, good intercooler, gt30r .63/.70 A/R, head ported to 27mm/25mm cams, 7,6:1 compression: not sure... i've a bd16+ inlet here... but not sure if use it....

the most importand thing for me is to get some help with the ignition map! (fuel is no problem...)

optimum AFR and exhaust gas temp would also help

thanks!!!

 

i couldnt guess at an ignition map for you as ive never wrote one for that spec of cosworth,,, it going to be a big power machine,, it would be better to let a tuner write the map for it

as for fueling,, you wanna aim for about 11.7:1 for peak power

 

...I'm from Austria and we don't have many cosworth tuners here i don't need the full map... but some ignition points like 6500@1,6bar would help me a lot...
