Currently just finished install and was curious if anyone here has any insight on the fuel side of tuning. With the serial number on fuel pump sheet it states to use -19.5 overall fuel trim with the use of 1350cc injectors or hondata injectors but nothing for 1650cc injectors. Im not looking for this to be an end all for as a tune but just trying to get a good base. Currently still waiting on the bigger maf housing and and p600 turbo before getting an actual dyno tune.

Sorry to be the bearer of bad news, but 1650 doesn’t work on Hondata/Bosch currently. Not enough room to scale it properly. 1400 is as far as you can go before needing Motec.

That is definitely bad news I'm not goin to lie. I purchased them due to them saying they are supported on the oem Bosch ecu.

Ordered from 4 piston but came in xdi box with their calibration sheet
Yikes, hopefully 4 Piston will take care of you. I know they sold an Accord owner a pump that didn't fit (he claims they told him it would) and wouldn't accept it back.

That’s rough. On their website it says it can be supported. This is not good news as I have an XDI pump on the way and I was literally about to order the 1650cc injectors

On a side note for people who haven’t bought injectors yet. The hondata FSU runs fk2 injectors so do with that information what you will
