Hi there, does anyone know about the different companies who does upgrades for the stock 20B ECU and the costs of it as well? I noticed recently on eBay that a guy was selling a 20B with tranny all modified and the ecu was upgraded by Pan-speed. I was wondering if anyone knew how I could contact them to get more info. on this.

Thanks

 

Well, if you want to keep the stock ECU, you've got to keep the stock (auto) tranny. This poses a problem for most enthusiasts. Basically, if you want to chip the stock ECU, you're on your own in pretty-much uncharted territory.

Hey Brandon,

Uncharted territory is quite true indeed. Its a pity, somehow I feel of I was closer to Japan , it would have been a bit easier. If I was going manual tranny, I know I wouldn't have much of a problem to deal with....

 

Well I will correct you all right now. If you keep the stock ECU, you DO NOT need to keep the stock tranny.
I have a S6 5 speed gear box in my 20B JC Cosmo, I also run the staock 20B ECU!

 

Yo dude, you read me wrong there, I agree that the stock ECU would work with a manual gearbox. My problem is if I still plan to use the auto tranny, I must use the stock ECU, even if I want to run an aftermarket engine management , it'll have to be installed as a piggy-back with the stock ECU, just to enable use of the auto tranny. But briefly, what are all the parts required when going manual ?

 

so dude, more so my comment was at no7yet.

To go to a manual, in a cosmo?? You need to make a gear box cross member.
you need a gear box ( I went S6)
with S6 box you need to have the speedo signal recalibrated.
if you use a S4/5 box you just put the factory auto sender in the manual box ( a littl emod to fit)
You need cluch and flywheel
You also need to make a pedal for the clutch.
Then you need to modify the driveshaft to suit or simply use a 13B JC driveshaft

 

Hmmmm....sounds like a bit of work involved, I think I can get access to a S6 gearbox, flywheel , clutch , but the clutch pedal assembly would be a bit tricky. Can the Cosmo pedal assembly easily accept that extra pedal with no worries, and the clutch master cylinder too?

bitchen7: sorry to bring this thread back from the grave but can you tell me more about using the 20b stock ecu with a 5speed? everyone in the 20b forum swears that its not possible and that i would have to use the auto tranny. thanks!

 

im wondering the same thing. it makes no sense to me, there must be a way to make it the stock ecu work with a manual trans... does anyone know the exact reason the ecu does not work with a manual trans? is it because of the unconnected tranny plugs? can't you just prvoide the required signal externally if this is the case? there must be a logical explination and solution, i do not believe that it is impossible. i will find a way to use the stock ecu, especially since the only other option is spending 1,500+ on standalone

 

If a $1500 standalone (you can get a LTX12 cheaper than that) is stopping you from doing the 20B swap, you probably won't be doing it anyhow.
