Someone is converting their Starlet turbo Automatic to manual.

They're going to measure the torque converter fixings and I'm going to compare against the Seras [update: both Starlet GT auto and Sera auto share the same torque converter mounting points]

Starlets have different ECU's between auto and manual, whereas Seras don't. I have twigged that the Starlet automatic gearbox has extra features which are routed through the ECU.

I'm thinking if a 4E-FTE engine was mated to a Sera gearbox, and a manual 4E-FTE ecu could be used then it should be fine.

That's interesting! I guess the Sera was such a low volume car, it was more economical to use the automatic ECU in the manual version and not connect everything.

So that means a manual to automatic conversion in a Sera would be easy..?

Easier I think.

The Starlet manual ECU on the EP82 had 2 plugs, one 26 pin, one 16 pin, just like the Sera, with the exact same pin layout. Therefore its basically plug and play on a manual, and just swap things over in the engine bay

The automatic had 3 plugs, 26 pin, 16 pin and another 12 pin plug. It may be possible to use the auto ECU but not connect up the 12 pin plug that doesn't exist on the Sera just to use the manual ECU.

I have nothing new to add apart from having to try it out to see if the theory works.

I can't see why not!

I was thinking of how to convert a Sera automatic to turbo without changing the gearbox to manual

There are Turbo Starlets that are autos, so why is it a problem on a Sera?

I would use

Starlet auto flywheel/flex plate
matching starter motor
Sera gearbox & driveshafts
Starlet manual ECU

If you want struts I can send to Canada. Costs I have given over facebook. Payment can be by paypal to andrew@toyotasera.co.uk

That's handy to know
I was thinking that if my engine starts giving me any more trouble. I was gonna throw a turbo at it. But I would want an auto. This isn't a compromise ! Haha 21 and im already a lazy old man !

Why would you use a manual ecu with an auto box. Are they universal ?

As I parked in the disabled bay the other day someone shouted over

 

"Hey, what's your disability ?"

 

I shouted back, "tourettes now F**K OFF !!"

The automatic starlet turbo has a 'power' mode on the gearbox which is controlled by the ECU. The Sera doesn't - the ECU's are the same manual to automatic. The manual Starlet ECU has same wiring connections as the Sera. The Starlet Turbo automatic box has an extra 12 wires going to the gearbox via a dash switch and a warning light.

The Starlet manual ECU + Sera auto box should work fine and should be a lot easier to install.
