I recently picked up a pr4 automatic ecu from a 92-93 Integra.

I have been reading up on the ecu and I am not 100% what is needed to have it chipped, run 5 speed and enable vtec.

I understand the chipping part and how-to convert to 5 speed.

But I'm confused about the vtec add-on. So in order to have this obd1 vtec 5 speed, I will need to have a chip installed, jumper (for 5spd) AND the vtec add-on?

This is what I was thinking I need for vtec add-on:

Would this be the same concept of p06-p28?

I tried to search but I've yet to get the hang of the search engine on this site after the big change.

 

You will need a vtec conversion kit: http://www.phearable.net/shoppingcar...ion-p-121.html

You will need a Chip Kit with a vtec basemap for your engine:

Yes same concept as the P06-->P28, as these ECUs all use the same basic board layout and function.

To chip and convert your ECU you would need both a chipping and VTEC kit

I'm in a similar sitiation as the OP but I have a P75 ecu with a Hondata S100 system already installed. I want it to run my lsvtec, so I need to convert it to vtec. Would the vtec conversions u guys sell work for this and all i'd need after that is a vtec map loaded for the Hondata?
