just wondering if anyone knows what is the best ecu to be running on a b20b in a 91 Da6. I've been using my ls ecu and it runs pretty lean... I tried swapping the injectors I'd been using to H22 ones and now it runs a little too rich so I lowered the fule pressure from 65 psi to 33....is that safe?..... after that it runs fine most of the time...any suggestions for my noob ***??? ... also what are some perks and flaws on having Crvtec.... I heard it was very unreliable....

 

i would recomend using uberdata/chrome or whatever stand alone system u should choose to get the most out of your engine. Cr/vtecs are like anyother built engine. They will only hold up well if you build them well and take care of them. If you do it cheaply you will end up with a cheap engine. b20's do have thin cyl walls so if your keeping stk sleeves you probably will not want to rev more than 8,500 rpms. If your using the h22 injectors should be sufficient for your current set up, you just need to tune your ecu for them.

as for fuel pressure 30-35 psi at idle with fpr vac hose disconnected would be sufficient

 

i might be wrong but is this setup for B20vtec or straight B20?

 

stock b20b... just wondering if crvtec would be a good choice.... or just slap on a turbo... but... I'm more of an n/a fan
