I dunno, I think the rods will handle some power, but I fear that the stock cast pistons will warp or crack under the heat of turbocharging, I can set you up with a company that sold me some custom pistons, I have yet to install them but the quality looks fantastic compared to the stock pistons.
This is why it's crucial to have proper engine management. I know in most cases lean is what we want; but, while Kyle's testing higher boost and trying to reach his goal of 300WHP he's gonna have to run as RICH as possible with the least advance possible. That's just how it's gonna have to happen at first, otherwise yes the bottom end will bust. He's running around 5.8psi right now, and he's probably gonna have to run at 10psi to see 280-300whp who knows exactly how much it will take to get a solid 300. Boosting around 10psi, that's around what most other Hondas can safely take and it's not really that extreme but in our semi high compression engine it's definately enough on a stock bottom end. I can't predict the future but if Kyle gets the proper management I know the final number will be impressive but how impressive is the question.
 
I have seen that in all the threads in the g2 performance section, it all seems to come down to mangement, the AEM stand alone ems would solve all these problems, I am just starting when it comes to performance mods and learning all I can about engines, espeicially ours. That one member awhile ago said he ran a AEM EMS didnt he, if i am not mistaken, but has since stop posting and we never recieved anymore details. The universal ems is about 1200 right? If anyone knows of any place that can install and tune it in new england by the mid of summer I will save up and buy one and hopefully also have enough to pay someone to tune it to run a stock type 2 6 speed coupe, and I am sure once this is done, correct me if I am wrong, anyone else that would want to run the ems could use my base maps and codes from mine so they would not be starting from scratch correct? I really want to help out with all the great work you all have been doing recently, my expertise is plumbing and hvac, not cars but I am learning. So if anyone knows any place in new england that they think could tune from scratch with the AEM stand alone EMS let me know and i will gladdly try and get this done for the community, I am guessing a tune will rune probably atleast 1000 probably closer to 1500? I am not really sure what could I expect to pay for it?

Shaylord, yeah that would be cool if you'd get base maps. NO NO NO it should not cost $1000 for the tune, because we can use an NSX AEM base map as a precursor to our basemap.

That guy Buzzard is the one who uses the AEM standalone I believe or at least he can make us adapter harnesses.
Have you seen the thread about chipping our stock ECUs? It has some really good info in it. I bet with the info in the thread I just mentioned, an AEM base tune for the NSX and your car on a dyno/wideband it wouldn't be that hard for the guy to tune your car, at least to stock anyways. Now if you're wanting to make multiple pulls to try and gain some numbers it may be more expensive.
 
buzzard uses something other than the aem I cant recall what it is off the top of my head, i just remember it wasnt the aem, does anyone know of a good tunning shop in new england say boston ma or manchester nh area?

autotronics i believe... he's also dealer for them
 
so where'd the guy go that started this thread, and what's up with the turbo?
 
no, but he has not commented once through all of these posts......
 
sry for time away from acura-legend.com i was just busting my ass at work and school so i really didnt have the time to go on... but yeah i just got my turbo yesterday.. it looks pretty sick.. but i have to wait on some more parts (wastegate,BOV,flanges,etc) in like the middle of may i should have like 70% of the turbo setup done.. then i have stop it from there due to the fact my engine has F***ed gasket and its over 190 000 clicks im gonna have to save money for a type II motor so around the end of august i should give u guys a clear view where im at...

I doubt that we are going to be able to use the NSX base map as a pre cursor, its lookin like we are going to have to base tune ourselves, unless there is some way to take the stock ECU base and program it to the AEM, the NSX base tune is miles away from our base tune. Unless of course we find some way to piggy back the ECU via like an emanage or something, I would suggest using a cheaper stand alone before jumping into the AEM. Just my $.02.
Actually the NSX base tune is very similar to ours. Read the thread about chipping the stock ECU's; the Bayou chip is based on the NSX ECU not ours.

The NSX uses almost identical fuel maps as the Legend up until almost EXACTLY Legend redline which is around 6500 Rpm, after that the NSX reverts to a seperate fuel and timing map which of course would be while VTEC is engaged.

Now I know all of what I just said has nothing to do with the AEM, but as far as a solid base tune for the NSX is concerned it should be very close to the stock ECU. Now this of course is just IMO but I believe that you could use the AEM NSX base tune and literally plug and play to some degree, reason being that non vtec fuel maps are very similar for stock and since the Legend cannot surpass the non vtec fuel map redline (~6500 a little higher in the Type II) it wouldn't ever need to engage that map.

the guy that used the NSX AEM standalone on his Legend had to basically retune everything, the base was day vs night, maybe that was just one person, we'll have to see what happens. As far as the Bayou tune, alot of Bayou users say the Bayou chip runs pretty rich, and if it is based off the NSX that would explain why, I think the Bayou chip is one that needs a cam and port work in order to run efficiently.
Yeah, don't get me wrong it's definatley not the tune you'd use, but I know now they have enough similarities that it would make tuning easier. I mean whoever that was that had to retune everything, wouldn't you rather retune than tune from scratch? Maybe it was just him; I dunno we'll see soon. As far as the Bayou tune, that's probably exactly why it runs rich. Beav the guy who has been studying the .BIN files for the bayou said it's nothing more than the NSX map changed around in a few places to compensate the Legend.

I mean, it makes sense that the tunes would be at least slightly close. The blocks and running tendencies are very alike under 7,000 RPM. The main reason the NSX block makes more power is because it can rev higher since it has the shorter stroke and DOHC, and of course the VTEC is a big factor too. If we could adapt NSX crank, rods and pistons that alone would increase our redline; we know it's almost impossible to use the heads and go DOHC so that's out of the picture.
 
My 2 cents

Why anyone would go with AEM is beyond me. There are many and cheaper kits out there. I personaly like SDS... have used on many cars with no issues. As far as turbo location there is the remote mount option. STS came by the shop with a demo truck and I have to admit... when I saw the setup I was like.. "Whos back yard idea was that?" After a ride and seen the truck on the rack... it worked out very well.

Reason why the AEM looks so attractive is because of the NSX AEM EMS. It's a dead ringer for the same ECU,harness, and connectors as a Legend. There are different wires going to different places but thats not nearly as much of a problem. As Imran pointed out in his AEM EMS Legend thread and much follow up research ive been doing, the NSX base map should get the car up and bearly running once a few wires are addressed. With an experienced tuner on a dyno that should cut tuning time and save money Vs. a from scratch system.

Once again all we have here is some fact but mostly speculation because, theres only one person thats done the full management in a Legend and that guy hasnt elaborated on his setup publicly since he said he did it and it works.

If you understand the way the systems work then megasquirt, uberdata, modifing the stock code, ETC. will be a peice of cake, for the rest of us we need something a little less daunting, like the AEM.

I agree about STS being a good company and an inovative way to build a turbo system. I think you'll always have 30% haters with whatever you build as long as its not 60% bad and 40% good then it all good.

It does not get any easier than this... http://www.sdsefi.com/

Look into it... real user freindly
Will these pose a problem on a Legend Engine?

# SDS is not compatible with OE crank sensor systems.

# Not compatible with OE air idle control systems.

I dont want to learn how to figure it all out, i want a tuner to do that on a dyno. Is that bad of me??

Nothing to learn. You just index the crank pulley and install a magnet

The IAC system would be thrown out. They have a cold start setup in the unit if that is the concern

And no it is not bad of you.... the shop I work at... we deal with that every day. Lots of people do not want to do the work themselves... hell that is why we are here

Badboyr66,

I would probably have to say that the AEM seems to be more of a guaranteable street system, as to where the system you have shown looks to be slightly more geared to a race application. It does look cool though and I saved it to my favorites.

The thing about the AEM is like DV8 said, we can use the NSX base tune to at least get our cars up and running and then tune from there. Now I know you're a noob but I was wondering how much you actually know of this systems compatability with Hondas especially Legends. Reason why I say this is because our car has so many differences compared to other cars that nothing else has previously been what appears to be so easy to tune with (as seen on the website). I guess what I'm asking is what gives you the ability to say that it would work on our car (EASILY and EFFICIENTLY), is it knowledge of the Legend or an extensive knowledge of the product that tells you this could work on almost any platform?
