How to set dwell settings with a Toyota "smart" ignitor

[Danbob]

Hello, still slowly getting my settings understood and dialled in on MS3x setup.

I've found out my Toyota single coil distributor driven ignition (Gen3 3SGTE) Uses a smart ignitor which calculates dwell itself, meaning I do not need the megasquirt to do this.

In this case how should I set up the ignition dwell settings in tuner studio? Unfortunately there is no reference I can find to how to set up dwell for a "smart" ignitor in the TS or setup manuals.

Thanks in advance
Dan

We just ran those with 2.5 ms of dwell on the MSPNP. That's what the stock ECU did.

Hi Matt thanks very much for that I'll try 2.5

Hi Matt, was that 2.5ms dwell using the "standard dwell" setting or one of the other ones?

Also this is using a later 94+ MR2/Celica ST205 igniter which is apparently different to the earlier one (although appearance is same). Did the MSPnP settings work with the later models aswell?

Thanks again
Dan

Correct, that's standard dwell.

We haven't seen any difference.

OK thanks, this sort of info from somebody who's done it before really gives me a lot more confidence!
