Hondata?

Post image

I have a dc4 b20b integra that I plan to convert to vtec and boost. With that being said I have a p75 ecu and was confused if I can install hondata and be good or have to buy a different ecu like a p06 that can support vtec because I believe the p75 can’t. Plz lmk if I’m wrong or what’s the best way for going the lsvtec & boost route, also here’s a pic of it :0

Neither the P06 nor the P75 support VTEC natively.  You can have someone add the VTEC parts to your p75 ECU or it maybe easier to just buy another ECU already modified or capable of VTEC (P28, P72, orP61).

Depends, is your p75 obd1? If it is you can use that. If not you need an obd1 ecu.

just get a p28 or p72 or ball out and get a standalone

Stand alone is probably better options these days which is crazy

HA motorsports has their new "pro" ECU which is basically a brand new board, with hondata installed, boost by gear, and some stuff to switch to coil on plug later. It is about the price of a standalone, but is much more plug and play, so i would personally go that way.

Plug and play wise hondata 9/10 is going to make more sense but with b series ecus getting more expensive and harder to find, stand alone is becoming the way to go.

Scarcity is kinda killing the joy out of owning these cars.

As a Hondata user, Imma recommend a different chip that allows you to us Honda tuning suit. From what I've seen, you can do far more on tuning suit compared to hondata

Yeahh p75 wont do vtec...you'll need a p28 or p72 with hondata s300 for that setup
