Good morning everyone ....
My name is Marcelo, Curitiba/Pr-'m from Brazil, I'm riding a MS-I in a Gol CL 92 2.1 8 valve engine, the problem I'm having is the following, which is the fuse between MS-I and coil (MI 2 wires) is burning, and using Tuner Studio, TPS sensors, water Temperature, Air Temperature with the measures are all wrong, so before you even start the engine, only with the key turned.
This same injection was already installed and running in the car before, however as we modify the design, uninstalled it, bought new whip, rode the new engine and reinstalled it, but already checked all cables from the harness, all connections, was used diagram supplied on the website of MegaSquirt, and we do not know what else to do, if anyone can help I appreciate, I apologize for my English ...

Thank you,
Balz, Marcelo.

If the MegaSquirt is not controlling ignition, please make sure that you haven't accidentally grounded the coil negative terminal.

OK, I'll check in any case, this diagram was used to install the MS1, is that correct?

If you are installing a unit from MegaSquirt Racing, use that diagram. You might want to contact them for support, as well - they'll have a better idea how their units should be wired up. If you are installing a standard B&G MS1 (fuel only, coil negative triggering), use this diagram.

This does not appear to be a standard MegaSquirt. If it is a licensed version for the Brazilian market, you need to contact your supplier.
