I'm not sure if this will be any help at all, as this guy problly wasnt running the auto transmission.... but he did get the stock computer to work:

From lance's site:

Bullshit. This isn't a playstation we're talking about here you can't pick up a 20b mod chip off ebay. What he would have done, as I *think* evil aviator was alluding to was to keep pulling codes and dummying up the sensor until he found the one that it had decided was critical. He didn't modify the ECU, he modified the loom to trick the ECU.

This is where a service manual comes in VERY handy. They are available.

Stock exhaust valves cause no problem. we have fitted a big bore exhaust to our Cosmo and never conected anything back up and have no problems.
if you believe the factory ECU won't run the 20B without the auto, call Ray at Gizzmo Vehicle Electrics here in NZ.
0064 9 818 2099, remember the time difference.
This is the guy who did the ECU wiring for Lance Warren (www.3rotor.com) HB Cosmo 20B. I think they ended up with about 10 wires coming from the ECU, so the article on the car in a local mag says anyway.

 

Last time I heard, this car isn't running properly.&nbsp They couldn't even run it on the dyno.&nbsp Does anyone know of a more recent update?



-Ted

 

Go talk to Paul Ko about this.&nbsp I dunno about you, but we got the old K2RD white FC to drive around with the 20B up to about 4kRPM under one night of very rough Haltech tuning.&nbsp The car, at the time, was able to crank, start, and drive around the parking lot with very little fuss - this was before we trailored it down to 7Stock IV.&nbsp What have YOU done, Mike?


-Ted

 

ted, if you wanna step outside we can, but this thread is not about our difference of opinion. i would like to help now get his car running on the stock ecu. if you dont i have no problem with that.

mike

 

quote rmp pwr"
MAP Sensor - mazda loves them so I bet the 20b uses them. Obviously it's best to check the voltage at the ecu pin but there's even easier ways. If you can actually get the car rolling you can open the throttle until the boost gauge reads dead 0. If the car pulls fine then but bad either side then the sensor is dead / open.
"
ok with the boost gauge now connected I can see
exactly what rpm is saying,,, as soon as I see " 0 "
it dies, I can rev it in neutral no problem but as soon as I load it dies at " 0 " .
i will do some testing tongith and see what readings i
get, i might have to ask how and what to read though.

matt

 

Ted, do you have any pictures of your 20B FC?

 

Not to step on RETed, but here is the link. LOL, I thought that everyone here knew about it since it's been on the internet for over a year now.
http://www.k2rd.com/Projects/20B/20Bpics.htm

Yes, the new owner is still working on it. The main problem Mariah had was trying to sequence the turbos. BTW, that car has a TECII EMS and a TII MT, so I'm not sure why RXTRA7 posted that link in this thread about running the 20B with a stock ECU and AT. PFS has built several 20B cars with the Electromotive EMS units, so I think that it's well established that the Electromotive units work, and others have successfully used the Microtech, Haltech, Motec, and Wolf EMS units. It's the stock ECU that seems to be the problem.

 

It wasn't my "car", but I own the engine and all the electronics.&nbsp As of this moment, the engine has been removed from that particular car.&nbsp I have no idea what the plans are for that particular vehicle.&nbsp You can contact Paul Ko @ K2RD and ask him yourself on his plans...



-Ted

 

"In November of 1995 it was decided to totally re-think things to overcome the cooling problems."

It sounds like they gave up?



-Ted

 

So Ted, that is your engine? can you tell us where you got the gilmer drive pullies from?

 

Actually, I think that engine belongs to another forum member that I talk to online all of the time. He has it out in Hawaii and building a killer widebody FC with it. I was also told by someone that THAT Gilmer drive setup was just to look pretty... the teeth didnt even line up correctly and would have broken the $120 belt if it was ever turned over with the Gilmer setup on it... Any truth to that?

Evil Aviator:
THAT is why I was asking about Ted's 20B powered car.... I knew that K2RD had a 20B project vehicle that Paul put together, and Ted probably helped with as well, but I wondered if he had his own...

 

So, this thread has gone a bit off topic here.... sorry bout that.

Now:
Good luck with getting the cosmo ECU to work. If you go to the site that was listed about the HB from NZ, send them an email and get their phone number. Then go to google and search on "long distance new zealand" and use one of the super cheap calling cards (I can call there for 8 cents a minute) and talk to those dudes.

Of course, check for intake leaks and all of the other stuff suggested, but those NZ guys may be able to help you out... If you still arent having any luck, email hitman@hitman.hm and ask him if he knows anyone that has gotten it to work.

Sorry I'm not much help on this one... but I'm avoiding this headache by using a Haltech

 

I did give the NZ guys a call and they gave me a couple
things to try, ray was very helpful and offered to help
more if I needed it.
calling there is not as expensive as I thought its only 58
cents a min,,, or for calling plan customers its 25 cents a
min,,, not to bad to talk to someone on the other side of
the planet, who have a wealth of knowledge and are willing to help

matt

 

Yes, that is my engine.&nbsp I paid for it - I own it.
The Gilmer drive system was something Paul Ko was messing with at one point.&nbsp I don't want to say something wrong (as there has already been negative comments on it already in here), so I must default to recommending to contact Paul Ko @ K2RD for more info.



-Ted

 

That is correct.&nbsp The engine is presently taking a vacation in Hawaii.&nbsp I think I already stated that somewhere else.&nbsp It is still my engine - it has been "donated" for that project.&nbsp I haven't been too detailed on what was going on, but we were trying to keep everything hush-hush.&nbsp If the cat's out of the bag...


Like I said in a previous post, I would default to contacting Paul Ko @ K2RD for more info.


Currently, my efforts go to the "new" project car in Hawaii...
We're shooting to get that car up and running by the end of the year.



-Ted

 

reted,,, I hope you have had a chance to read test drive
part II,,, things are not looking to bleak,, I think
you might have been mistaken about it not being
possible, since I seem to have it running good now.
One could say"
If at First (person) doesn't succeed,, may a better one
try again " LOL

no offense intended just taking the opportunity to be a smart ***

matt

 

LOLOL, I hope you documented all the steps to get it working so other people wont fall victim to the overconfident persons saying certian things are "impossible". Congrats, now take that auto tranny out.

PEOPLE FOR THE RECORD!!!
now has done the 3 rotor engine swap for under $5000! It is possible to have a inexpensivce 3 rotor FC

 

Oh, I've read it - I haven't commented cause I don't have anything constructive to add.&nbsp Now that you've directed the comment towards me...

I still think the whole thing is a big waste of time.&nbsp Banging on the firewall just to make the auto trans fit may have compromised the unibody of the car.&nbsp A manual transmission would've worked fine, but that's not the option you took.&nbsp The auto trans cannot handle that much torque, so you're limited to how much power you can produce.&nbsp Running under 400hp on a 20B is a waste of a 20B in my book.&nbsp Most people can't track down the stock ECU OR stock coil packs OR stock AFM - these items are rare or just plain impossible to secure, short of getting a front-cut.&nbsp I think we can count on one hand the number of people who have just the stock ECU?&nbsp What's going to happen if you run into problems with your stock automatic transmission?&nbsp Are you going to try and find another one afterwards?&nbsp That's one hassle I don't want to get into...



-Ted

 

Banging on the firewall won't "hurt structural integrity" to any noticeable degree.

The automatic won't take the torque? What, nobody modifies 20B Cosmos?

 

peejay> said some of what I had to say.
the rest is that I put the auto in to see if I could do it!
(get the 20b to run with all stock parts)
If I want to put in a 5 speed, or better, in the future
there is nothing stopping me from doing that,,, and
you know what,,, if I do go with a manual trani,,,
I am going to prove another point,, that you can use
the stock computer with a manual trani !
It has been done. I don't plan on doing this for some
time, if ever depending on how it goes with the auto,
but if the auto does die,, well it will speed up the swap
to the manual.

matt

 

Greg I wish I could say that I did this for under 5000,
but it has cost me a little more than that,,, why? you ask,
well I paid a high price for a Cosmo clip that was "good"
and known to be in running order, that came with a
warranty (for what that's worth)
and the car I am putting it in, I paid top dollar for that as well,
the 88 ae, is in really nice shape rust wise and will last a
long time, and might even sell for more with the 20b in
it if I ever sell it. (doubt I would sell it though)
but yes it can be done cheap, I could have gotten a 87
TII for 1200 Canadian and a front clip like someone else
on the forum did for under 5000 Canadian which would
= a cost in u.s. dollars of about 4000.

matt

 

Sure, with limitations to the set-up...
I'd like to see the car dyno...


You might want to consult with now first before making false claims.&nbsp The front cut has to at least cost $5,000, so that makes the rest of the project free?

I'll put up this challenge - if you can build a 20B FC for less than $10k, I'll PAY YOU $10,000 CASH for the car that makes 500hp and can run 20,000 reliable miles.&nbsp If you're so confident you can pull this off for $5k, then a 100% profit should be sweet, right?



-Ted

 

Sure...
Building a 700hp 20B FC will have no problems with someone banging on the firewall...
At least I know who not to consult on automotive structural integrity.


No, they don't.&nbsp The car was a flagship luxury car in Japan.&nbsp Why would a 50-year old executive wanna build a street killer...
