Engine won't rev above 6000.

Post by andylc99 »

Just setting up my first Hondata ecu.

Been through a lot of the forum to try and find all the answers I need but can not seem to resolve the problem with the engine not revving above 6000 when under load.

UK Civic EP3 Type R with TD03 turbo, 4bar MAP sensor, 550cc injectors, AEM AFR input on channel 0.

I have attached my tune and a data log, any ideas?

Your wideband seems not to be functioning right base on datalog

Can Hondata explain why is the s.trim -27 for such a lean A/F, 19.27 according to the analog reading.

Start by figuring out why the aftermarket wideband is not working correctly as the will probably lead to the resolution of the issue.
