How is the new ECM coming along?

Is it playing nice with the CCM?

Jeff, I think you want the TT more than I do.

NAH, more curious on the ECM piece of it honestly..

Although a TT would be nice

The report from Megasquirt on Monday said the car was still on the dyno. They are working the base tune.

Yes, the ECM is talking to the CCM. They've only sent test data between the two just to verify the connection and format. They'll work the packets next. Confidence is real high that this will not be an issue.

Corey Henderson spent some significant time with them discussing some particulars. We had some concerns on the 1990 MY (just for you Brett) because of the differences in Spark Control. We want to make sure this thing works with all years straight from the box...

The first ECM is going to Ron Bidwell and his car is a 1990. Corey will confirm all the functions and then tune for the twin turbo. We are still a few months from completion. I think we (Ron, Corey and Megasquirt) would like to have all completed before BG.

I have my fingers crossed!

Cheers,
Ron

Car is still on the Dyno however they haven't ran it for a few weeks. The software guys are trying to improve on the way the secondaries sequence in. They don't like the way GM did it... I guess it will take a firmware change from what I'm hearing. So now it's in the software engineers court.

Cheers,

Probably do not like the way GM (adjusts) half's the primary injector flow and turns on the secondary injectors at that rate then applies the fuel table from there. Recommend they just make adjustments that turns on both injectors all the time as does Tod P in his modification of GMs code.

Tyler,

R U saying Todd runs both injectors even at Closed Throttle? Stock code allows both injector ON after what is defined Closed Throttle in the cal. What would be the benefit of running both injectors, at half value, for idle?

The stock calibration does not turn the secondary injectors unless it meets the parameters to go to the PE mode, I think it cuts the time to .57 of what is commanded when in single injector mode. You can also use this parameter to increase fuel if your PE table runs out of fuel. I recommended this to Jim Smith for that on Ron Ks car as he was leaning out on the dyno and would not respond to additional fuel increases in the PE table. It worked but he did have to go back to the PE table and pull some fuel out at top end.

My car calibration runs both injectors at all times. Throttle plates are removed. With the code mod you cannot jump back and forth. It does not matter whether you run one or 2 injectors you adjust the calibration in the code to meter whatever fuel is necessary, WOT or idle.

By "code mod" do you mean changes in the calibration values or modification to the ECM code. My motor has throttle plates removed, however at Closed Throttle, only the primary injector functions using VE Closed Throttle table.
I just want to understand what would be the benefit of running both injectors at Closed Throttle.

Modification in the ECM code. If you do not do this mod you only run on both injectors in PE mode.
