I dropped a 92 F22a6 into my 90 accord. Im using the pt6 from a automatic. My tach doesnt work until 4 grand. Anything under and tach is dead. I read that when coming to a stop the ecu will be searching for a load and the idle will drop in stages. Which its doing. I was curious if anyone with this type of swap is having the same tach issue? I will be ordering a manual Pt6 ecu in future.

It does not matter if you use a auto or manual ecu.
I did a auto to five speed swap on my cb and I am still running the auto ecu with no issue. -
ur cluster itself is jacking up or not getting a good enough signal. check your grounds.

That statement my friend is false. Running an auto ECU in a manual causes HORRIBLE MPG's, it also causes inconsistent idling, AND the powerband is different. All I can say about a manual ECU in an auto is that it also causes HORRIBLE MPG's.Originally posted by thepowderblue View Post
The idle dropping down is DIRECTLY related to the auto ECU, mine did it to me as well. It's the computer looking for the load from the tranny, it uses it to level out the idle. As far as the tach, thats either a bad ignitor, or a damaged cluster.Originally posted by kirk90 View PostLast edited by dj_ender; 12-31-2011, 09:04 PM.Originally posted by Mishakol129Comment

Power is there but not like thought. Idel is fine and mpgs are good. I went 160 miles on $25.
Ill swap in a manual ecu I have and seeabout the power.Comment

On my auto ECU the powerband dropped off DRASTICALLY almost dead on @ 6k, with the manual ECU it pulls hard to 7k. With my auto ECU ( and the person I bought the manual ECU from ) I got about 300mi per tank, now with the manual I get close to 380.Originally posted by thepowderblue View PostOriginally posted by Mishakol129Comment

I am still confused about the whole different tunes on an auto vs manual ecu thing.
It just doesnt make sense to me. I man Honda would have some method not having a really bad idle while you are in neutral in an auto, just like you would be in a manual. I man if you drive an auto and pop your ebrake on and throw it in neutral does your idle get messed up?
I would think not. Also putting different fuel maps and most of the ignition table should be the same. Even if the auto shifts earlier it doesn't mean the engine map would need to be any different
Base idle on the auto may be set a bit higher, but the iacv should be the thing accounting for the load and adjusting. To my knowledge there is not seperate idle routene that looks for a load in civic ecu, they use the iavc, and eld to adjust for changing conditions.
The only thing similar to that routene would be one in Neptune which changes the iacv duty cycle for ac turn on. They could use something similar to this, but I would think it would be in both civic and accord ecu. I will ask over on ht tuning, but I don't think it is
Lol told you I was starting issues on the forum today

Don't listen to the guy above me, I have more posts then him, and my car has more HP, therefore I am right!
Prove my ecu map theory wring Jason!!!!!!!
Also Happy New year!

Shut up. you have a h22, rosko racing euro r IM, bisi header, and a custom tune on e85. your babble is pointless in this thread. go away.Originally posted by Mishakol129Comment

Now that ive cleaned up my mess by posting the same thread in two sections. My bad! I do have a considerable power loss and mpg sucks!. With the tach. issue, it wasnt there on either of my cars before the swaps. It had happened after swapping. That is why I had asked if anyone else had same issue. The only differences are pt6 ecu in a manual and I used a internal coil dizzy that matches with the 90 accord engine wire harness. Now my mph guage works fine. The tach stays at 0 till I hit about 4000rpm then jumps to that and climbs with no issues. The only reason i had revd that high was to see if the tach would move at all. The dizzy is about a year old. I will trace down some wires and see if maybe a ground issue?

dont think its a ground. it sounds like you have a loose connection or a bad sensor in your dizzy. is there oil inside or anything? anybody near you that would let you swap dizzys to see if its the problem?COUPE K24

But seriously I would be surprised if there was a difference, but I am often surprised
People are digging into the stock maps so maybe we will find out someday.
Jason, do you still have your auto? I want to dyno it with both to prove you wrong!Comment

there's a difference, thats why multiple people are having the same issues. or are you just president Clinton and can't admit the truth?Originally posted by Ghetto_CB7 View PostHurt my feelers...
