okay my friend and I installed a Greddy Turbocharger on his zc engine for his Crx. Well we are having problems with it bogging in 1st and 2nd but during high rpms or 3rd-5th gear its fine. And also We are getting codes 1 and 5 for a M.A.P sensor and oxygen ratio is not correct. The ECU is re-chipped(mugen) for the Turbo for DSM 450cc fuel injectors in 25psi of fuel but it still runs very very rich. So we put the stock injectors back on and now we are still running very lean with 50psi. There is a Fuel pressure regulator that is adjustable but it does not help at all. Maybe we are just running the wrong injectors. Can you guys help us out?

 

its fixed.

 

So, what was the solution to the problem?

 

modified the map sensor. rerouted the vacuum lines. reinstalled fmu and 450 injectors.
