Review: Motordyne E370

modme

Allow me to show you how Uprev's Osiris works. When you flash the ECU using Uprev, you use a ROM file. Here is a picture of what each ROM file consists of:


As you can see, each ROM file contains Fuel Tables, Ignition Timing, Cam Phasing, etc etc. It contains every parameter that the ECU needs to run the car. Every time you flash with a ROM file, every parameter is overwritten.

Now, in the OP's situation:
SpecialZ's tune: Will have revised Fuel Tables. But if the Ignition timing was not tuned, then it will contain stock ignition timing. Just because Ignition timing was not tuned, it doesnt mean it's missing from this ROM file. It just means it contains the stock ignition timing. Every ROM file has to have an ignition timing.
Church's tune: Revised fuel tables and revised Ignition timing, since both were tuned.

So the OP ran the dyno with Church's tune. He then reflashed the ECU back to the SpecialZ's tune. During this process, Fuel Table, Ignition Timing, Cam phasing, everything is replaced back with SpecialZ's.
