ECU Verification

[91-accord]

So the other day I looked at my ecu and the code read 37820-pt3-a23. So i was wondering if anyone can tell me if this is the right ecu for car (91 accord 4dr EX 5spd) because I'm concernned about my performance. Please notify me about this because I'm also looking forward to buying an ecu for a 93 accord ex code 37820-pt6-a52. Thanks

Dont buy an accord ecu buy a prelude one with an f22 just will get more power then the accord would give you.

Another ECU alone won't do much.

The PT3 ECU is the proper ECU for the F22A4 that is in your car. A PT6 is correct for the F22A6, which has a different intake manifold, exhaust manifold, and camshaft. Without those things, it won't really be an upgrade.

well i do have a few mods on my car. However, I swapped ecu's with my brother's accord 92 LX 5spd and my car felt stronger. That is why I figure if I use an ecu from the 93 ex, I will probably get a better gain than the lx and my original ecu. what you guys think.

[deevergote]

The ECU from the 92 LX is the same as the ECU from the 91 EX.

You may see a gain, but not much. Not enough to feel. If you feel anything, it's in your head.


And yes, the F22A1 equipped Prelude has a P12 ECU that has a slightly more aggressive fuel map.

i guess you're right about the gain. maybe it was in my head but before I could never beat the 92 lx until we swapped ecu's thats why I believed that I had gain. So p12 will be better than the 93 ex and will also be noticable in any gains?

what do you guy think of this ecu. its on ebay. but the thing is that I don't if its for a 5 speed. but anyways check it out if you have time. thanks
