i have a first gen b16a in a crx hf and i wanted to upgrade my ecu to something better, will a p28 programed ecu by kengy work Im pretty sure i have a pr3 ecu in their now

2ndGenT3g

go with a p28 it will work chipped or programmed it will do

chip your pr3 man mines chipped for high fuel vtec at 4200 and no rev i love it

i talked to guy at auto engineering he said i need to change my distributer and my o2 to a four wire o2 but he could be wrong

rangcrx

if you go obd1 he is correct and injectors

i dont really know what it is but id like to know every time i ask, someone tells me different do you know if there is a web site with some fax on obd series

If you want to run the OBD1 chipped P28 ecu, you will need to convert to OBD1 either via an ecu conversion harness, or cutting the plugs and doing it yourself. You will also need a 4 wire O2 sensor and an OBD1/2 distributor. The injectors are optional. I have the chipped P28 ecus and harnesses in stock if you need them and can offer more tech support if needed. Post up if you have any more questions or email me.

dude listen to jason on this, I just ( sept. 11) did my obd1 uprgade from a jdm b16 obd0 in a 88 crx si, and it was easy as hell. get an obd1/2 vtec dizzy ( you don't need the vtec dizzy but unless you want to do a single bolt dizzy get the vtec its worth it). and the wiring harness is so worth it. solder vtec ( 2wires) and o2 ( 4wires) takes like 10 minutes. dizzy swap, once you figure out the trick to get the pins out of the plugs, 10 minutes. o2 install another 10 min. time the new dizzy 5 min. misc stuff like pulling out the carpet to get to the ecu, and dealing with a stuck dizzy bolt. all together if you take your time and be careful with everything 1-2 hours tops.

I am an electronic engineer and read automotive wiring diagrams like a story book and I didn't want to deal with the rewiring of the ecu harness, def worth every penny.
