Need help with ecu codes

[Accord problems]

Hello. I just bought this 1991 accord from a teen.it came with two ecu. What one would be better to put in? accord ecu/ecm What is the difference between Than pt6 l10 and the pt6 l50 thanks.

[WagonLX]

I believe the difference is (and do'nt quote me on this one) pt6-10 is for manual transmissions & pt6-50 is for automatics. Both of these ECU's are for F22a6 intake manifold, camshaft, & exhaust. If you have an F22a1 or F22a4, you would benefit most from a pt3 or a Prelude S - p12. Just depends on what you have.

If you don't mind, if you could take the top cover off each, take a couple pictures and post them up it would be greatly appreciated.

Those are both ecu's for cars that have an f22a6, since the letter after the first 3 is an L, it means those are US California Emission Ecu's, if the number after the L is a 5/7/9 it means its an automatic ecu, otherwise manual.

So the L10 is for a manual, the L50 is for an automatic (Both California Emission).

Heres a little breakdown:
AAA-BCD
AAA = Ecu Model
B = Region (A - 49 State Us, L - California, C - Canada, G - Europe, 0 or J -Japan, Q - Australia)
C = Automatic (5/7/9) or Manual (anything else)
D = Revision Number

Dam never thought to look at it like that thanks. I have another question what is the best ecu to chip for my f22a . There is no number aftere the a

[deevergote]

No number means it's a Japanese engine. Should be the equivalent to the F22A6 (which would make those ECUs correct... well, auto for auto, and manual for manual.)

As you can see by cloudasc's signature, he's working on making the Accord PT* ECUs chippable. At the moment, the most commonly chipped ECU for the F22A is the P06. However, without a fair amount of modification, not much will be gained from a tuned ECU. The stock ECU tune is quite good.
If you don't know how to tune an ECU, you should spend some time learning... or find a good tuner to do it for you. Many people think you can just slap a new chip in there and gain a ton of power (thanks to bullshit ads seen on ebay and in the back of every popular automotive magazine.) That simply is not true. There are no safe bolt-on ECU mods that will gain you a significant amount of power. Many will actually do damage.

Ok thanks. I never thought to look at it like that. I have another question what is the best
Ecu to chip? I have a f22a auto. Ill be putting new rods and pistons 12:1 cam level 3 bisimoto and valve springs. Ill be switching cranke shafts . Dont know witch ones yet
With tein lowering coil overs and camber kit. Then the paint . Looking to see hp goals
Of 260 hp to the fly weal . Maby close to 200 to the weels. Is this posible with this
Setup? What do you all think . Please fill free to shair what setups have worked
Best for you. to make this kinda power . Thank you

As said above, the P06 is the ECU most often used. There is no "best"... essentially, the ECU is just a blank slate that you can tune. Just pick one that has all the features you need (or add them), such as IAB control, etc..
Most people here are NOT making that kind of power NA with an F22A. It's doable, but it will take careful planning. You'll want to have a good port and polish job done on that head.

Regardless, we're going well beyond the initial scope of this thread... and it's damn near impossible to understand you.

Well im sorry I dont have actual enternet. Im on my smart retarded phone from metro pcs. I will try to make it better

You're the one asking us for help. We shouldn't have to work harder to understand you because you can't be bothered to type clearly. If it takes you a little longer to type something we can understand using your phone, so be it. That's on you. You'll find that the more experienced members of this site won't waste their time helping you if your posts are impossible to decipher. I don't mean this to sound insulting or threatening... it's a simple fact. That's just how things work.

Well im trying really hard to be clear. And if some one wonts to judge for that them that
Is on them. I know my grammer is bad and im takeing classes for it. I do understand
What you are trying to tell me. Like I said I thank you for all your help.

I bought a P12 ecu from pull a part and I got it out of a 93 Prelude. Since mine says P12-A50 it means it is for an automatic?

[cloudasc]

Correct, since after the A, its a 5.

[WP'sFinest]

Correct, since after the A, its a 5.

Thanks man was pretty sure it was, just wanted to double check.

Why are the auto transmission ecu putting down less than the ones for a standerd?

[cloudasc]

Why are the auto transmission ecu putting down less than the ones for a standerd?

Its not the ecu thats causing the less power, the torque converter in the automatic transmission loses alot of power, were talking about 15% power loss from the crank, manual transmissions are only about 5%, both referring to front wheel drive, rear-wheel drive vehicles, and all-wheel drive vehicles have losses greater than this.
