Welly guys, and gals, i had the Type II engine installed in my car. I cannot tell a difference in power. I honestly cannot.

The intake looks more robust than the original intake on my 92 L , other than that everything looked the same. Some brackets had to be carried over so that it would work, also, some other stuff i cannot remember.

it runs good, nice and smooth, but i just cant tell a power difference. Is this because of the stock ECU?? Oh well, i wasnt looking to hop it up, the original motor blew, so i got this one at a "fair" price, i think :)

Are you using a TypeII ECU??

labor was about $600

motor i got used for like $850


No, i have the stock ECU, i never wanted to hop this motor up, so im not going to change ECU, its my daily driver. I just thought with a Type II i would feel some what of a difference.

Important thing to me is that it runs really well, smooth, doesnt smoke, and feels solid.

:)


its an automatic.
 
cool to see that you installed the type 2 motor. Well as for me, i did feel a bit more power coming from the motor. I do have the bayou chip though. $600 for labor is not bad. I did mine for free.
 
well to tell the truth the engine is not at its original potential since you changed the engine withut changing the ECU the ECU is NOT a hop up part. its a necessary part to make the Type II be most efficient in its use of fuel and air.

yeah yeah, u know what i mean though. Im sure the Type II ecu remaps the fuel and spark curves, and extends the rev limit, but i did not want to dump any more money into it. I rarely take it past 4 grand, i just use it to drive to work and school.
 
It's not just the fuel maps and timing... it's EVERYTHING! It's your sensor readings which a Type II motor has different characteristics than a Type I! Heck, even your timing is off! With a Type I ECU on a TYPE II Motor, I wouldn't be surprised if you're running less HP than a Type I motor.

You know you are looking at potential problems down the road by driving a Type II motor with a Type I ECU.

Hmmmmm, interesting. I doubt its as serious as u put it. The car showed no codes when it was put on a scanner. So wouldnt the car be throwing codes like crazy?? As far as the timing, its just not advanced. Im a NOOB to legends, but not a NOOB to cars. The car runs great, feels great. It just does not feel faster, thats all.
 
Don't sweat it. You won't run into problems later on. The Legend ECU is highly adaptable and forgiving. My car is a real cluster now, I am running a AT ECU in a MT car. No worries, runs perfect. Anyway, people who regularly swap Honda motors already know Honda ECU's are fairly interchangeable. Of course, full potential is not realized, but for cash strapped or people with different ECU plans, it gets them by just fine.

I suspect the real reason your car does not feel more powerful has a little to do with ECU and alot to do with gearing. Type I AT sedans have the tallest gearing of all Legend models. So, a 91 coupe with the shorter coupe gearing is going to "feel" more power than a sedan guy. Oh yeah, the redline is a bit higher on a Type II. Higher redline and shorter gearing combine to make Type II much quicker. Your Type I ECU is not even letting the motor rev to it's intended RPM.

If you have no intention of making use of the Type II motor, you can continue to use the Type I ECU, unless you fail emissions.

If you want full Type II power, you will need Type II ECU and a differential from a Legend Coupe AT.
 
Ok am i the only one that reads all this with actual experience rather than assumpstions?

I think Takemorepills came the closest. The type I ECU will work in the TYPE I, II and belive it or not The RL TYPE II Hybrid. The ECU is real forgiving. THe fuel air and timming differences between engines arent that different.

Now we can all get technical, but when it come down to the plain facts, ive tested all senarios myself.

If you swap in a TYPE II into a TYPE I chasiss and keep the exisiting TYPE I tranny, everything is fine. Until that is, you put a TYPE II ECU in. the TYPE II tranny obioulsy has diffent gearing and different sensors so the shifts are irregular sometimes. mostly between 1st-2nd gear.

I dont see much difference between the two ecus to merit the MUST swap. I had a TYPE I chipped bayou ecu running my TYPE II swap for the most part and it ran awesome, 7WHP and 7LB-ft on the DYno. I changed over to the TYPE II chipped bayou and although i got an extra 500RPM rev-limit, the tranny messed up more often than not and i didnt notice any 1/4 mile times dropping.

NOW i have a TYPE I Stock ECU running my RL-TYPE II Swap and alls fine, trust me it hauls ass. Can wait to get the chipped one back in in a few days.

Id say for all TYPE II swappers, change the tranny over and get the TYPE II ecu or if the regualr tranny stays stick with the TYPE I ECU and have it chipped, if you really want things done right opt for a SAFC and have it dyno tuned.

My TYPE II swap back in the day didnt seem much faster to me either, and just like takemorepills says the diff and tranny have a big role, thats why same weight stock vs stock coupes sedans, coupes are always faster than sedans. the gearing is made up to utilize engine power better.

DV-8: Okay... If I got a Type II engine with the Type II tranny, would I still be able to run effectively with a Bayou chipped type I ecu? I wanna swap out the engine and tranny and toss in the type II engine and tranny. Is it necessary to use the type II ecu or can I still use my type I ecu with the Bayou chip? Thanks.
 
couldn't most of the ECU "problems" be fixed and tuned with a piggybacks...SAFC and an ITC? Maybe get a J&S safegaurd just to be on the safe side if were to really worry you.
Take it easy, Micah
Your timing may or may not be off I don't know legends very well but your fuel will most definately be off to some degree.....SAFC would help you out.

Im not sure how the Type II trans will behave with the TYPE I ecu. The engine wont have any problems but the trans might since using a TYPE II ecu on a TYPE I trans causes some 1-2nd gear sparatic slippage.

Timming is not an issue, fuel can be tweaked but in most cases the Stock ecu runs very rich, with the bayou chip even richer. When i had my SAFC tunned a while back they had to - fuel to get optimum HP and even then HP was marginal.

Curious- what about the GS Sedan tranny (TypeII), is that transmission's gearing like that of a Coupe?
OK, I have a Type II GS sedan AUTOMATIC. Do I also have the shorter gearing from the coupes, or is it the regular longer sedan gearing?

All the trannys are the same, the gearing difference is in the differential correct?
