I dont know of anyone running 14's n/a on anything but sbecII.

I dont understand what you are saying about sbec1

Our ECU's run 5800 rpm limiter atx and 6200 rpm limiter mtx.

I hope you don't mind a stupid quastion Brent.

What would happen if I swapped my auto ECU for a manual one? Would the ATX TCU be able to communicate with it OK and still function?

.... flame suit on

Interesting, with a little luck I might have a chance to dyne my van with both an AT ECU and an MT ECU... Right now I think just the extra 400 RPM may help hp a fair amount...

DYNO .... DYNO .... DYNO ..... like everybody else on PLANET FREAKING EARTH says it.



OK then.

So I see my question was already answered.

Maybe my van already has a manual ECU then. That really does explain a few things. hmmmm

Wow, have you ever considered anger management? I have answered this question before...

I wouldn't count on the factory gauges reading accurately. Years ago Gus Mahon thought his rev limiter was higher than what everybody was telling him it was. I believe he hooked up a scan tool and learned that his factory gauges were off. (I am assuming you are going off the RPM.)

I still have to test this, but I don't think the check engine light will work correctly if you have a manual trans ECU. On the minivan the system architecture is different, the check engine light is not directly controlled by the ECU.

There were no minivan manual trans ECU's for the 3L. There for it would have to be from a car.

Guess I will have to work on that with my tona, would love atleast high 14's someday!

I thought that was all that the difference was until you said your wideband picked up a fatter pulse. I'd love to find a 90 MTX ECU to try out.

I still have a 92-93 SBECII MTX ECU in the garage from a donor car, I can't use it, anyone want to trade for a SBEC 1 MTX?

Is there an extreme annoyance management? Yes, others have also been annoyed, by this dyne thing of yours. Whatever though .... to each their own.

No ... that's not it, and I don't want to discus it. Thanks though.

There was a 90 Daytona at the yard ages ago that I pulled an A543 from but no ECU sadly, that was already gone. I'm running a 93 Duster MTX ECU and compared to the stock auto ECU it runs way better. I only wish I could wind it up more than 6200 in first and second though.

[Ondonti]

6200 limiter just always worked better for me on shifts at the track. Especially at high altitude where I dont make enough power to need 4th gear. The 3.0 likes to run richer then many people seem to think is should be. Seems to run faster in the 12.5-12.7 range then the 12.9-13.2 range that the auto ecu put me in with the same fuel pressure. But 12.5-12.7 isnt "rich" for an n/a car, thats where most n/a cars make the best hp. I wish I had a laptop that wasnt such a POS so I could get the datalogs off it.

also
Just because nobody has run n/a 14's on a non sbec II doesn't mean you need sbec II to run 14's.

Greetings,
I have a similar question as the original one asked at the beginning of this thread. I am resurecting an 82 Rampage that I've had sitting around for quite a few years. I also have a wrecked 95 Le Baron automatic, new tranny, 3.0 v6. What would it take to put this into the Rampage? Will it fit without modifing the body? What kind of wiring changes needed to use the Le Baron computer? I want to finish this by the end of July, 2008. Any advice and knowledge is greatly appriciated.

[BAKES]

from what i found so far info so far is you will need auto cv shafts ,89 and older front mounts . motor fits in but is tight you will have to splice the 82 into the 94 engine harness and trans harness if it is A604 also you will need an 89 tbi harness from the bulkhead back and intank fuel pump

[BAKES]

does anyone no if an 89 v6 engine harness willl plug into an 89 omni tbi buckhead connector

[quikvett]

Thanks a lot for the info. I still have the complete 95 Le Baron so I could pirate some of these things off of it. Why would I use a TBI harness if the engine is port injected? Does it have to do with the crossover from the carbureted engine to the port injected one? Is there any schematics around to show which wires have to be spliced together? I have a pile of questions. I have been away from these type of cars for awhile and have been concentrating on vettes and boat racing, so I can use all the help I can get. Again thank you very much!!!

[BAKES]

an 89 tbi body harnes will supply power to fuel pump and plug into your engine harenss with less troubles
