Is it okay to use a b6 ecu on a bp?

Re: B6 ecu & harness to work with BP?
It'll run like crap if you dont use the right vaf and ecu. If the ecus and vafs were designed to run on different engines, they would have instead of paying engineers to come up with new parts. Shortcuts and making things cheaper is always better in their mind, not the best choice when doing a motor swap though.

Havoc13 (Alex) just got a BP swap on his 94 and it's not running right at all for what he's said and I hear. He's got the ECU and VAF now, he's just waiting on a guy to actually install them.

It`s going to work just not sure if there are any cons?
I dont even know why you would want to splice the harness. It is plug and play.
All you have to do is swap your engine bay harness (from the ECU to the engine bay) to the SOHC harness. You would loose out on using the DE ECU (94-95) there is no point to splice anything. What i strongly reccomend is that you swap out the ECU to a BP ecu, with swaping to the BP distributor and swaping to exturnal coil, with the VAF. you could go for the RX7 VAF. this ECU would bring up your red line as well. only down side is you might burn just alittle bit more fuel, but you would only loose a couple of mpg. I ran that set up on my 95' for quite some time. Its not as bad as everyone says.

Re: B6 ecu & harness to work with BP?
I now have bp05 ecu, harness, vaf, and disty
Re: B6 ecu & harness to work with BP?
Although it is another chassis, on a Mazda 323.
I have a B6 harness, using BP10 ECU, BP engine, had to run an extra wire from ther distributor to the ECU to recognize twin cam.
Also, like others say, I swapped for a VAF from an RX-7 II, just had to adjust the flap and idle knob on the throttle body. Car runs much stronger, 2ith lightened flywheel, header, cam gears, stage II pressure plate.
I recommend before doing this swap to get all the diagrams, triple checked them and have a plan of attack before doing the swap.
The car is fast, but it will never be a match against a LSVTEC civic. I always say the BP was built to be run boosted, contary to Honda engines with very weak aluminum blocks.
