Don't want to hijack Ron's fantastic thread, but just to clarify... the table in the stock calibration, if set to zeros, will open the SPT's with a throttle position greater than but not equal to zero. To open them at zero, it is a very simple one byte change to the instruction set in the operating code.

It's not necessary to open them at idle, but if you choose to do it that's how.

Todd,

Couldn't you do that by what you define as Closed Throttle in the constants?
Also, wouldn't the pulse width need to be pretty small if using both injectors at idle?

No, it is a straight up function of TPS %, nothing to do with the closed throttle constant.

the injectors have no problem controlling the pulse width even at idle.

Todd,

Thx for the clarification.

Just a quick update...

I talked with both Corey and the MegaSquirt (MS) Guys yesterday:

Corey said the engine is together and in the car. They are starting to piece the Raptor Piping together and will need the Turbo's and associated materials in the next week or so. Corey is also sizing the turbo's for the 368.

MS said the Ruby should be off the dyno today. They've cracked the nut on the secondaries and are happy with the tune. Next comes some road testing. All is on track for them to be at BG. I'm flying into Atlanta the Sunday before BG so that I can join the group that's driving the Dragon's Tail.

BG - Both MS and I will be giving presentations. MS on the ECM and myself on the Raptor Turbo Systems LT1-5. FYI, both Corey and I are shooting to have Ron Bidwell's car finished for BG however the MS guy's may not be able to meet the timeline that Corey needs to tune the car. We're pushing but it is what it is...

All in all, we are very happy with the progress.

Cheers,
RH

are you guys using the megasquirt pro?

more people on LS1tech are cranking out big power with these little computers on turbo cars. the features and affordable price is fantastic

wish I could make BG, please post up details of the presentation and keep us posted.

the turbo ZR-1 and the raptor solutions are exciting stuff!

1. Compatible with all Systems and Subsystems
2. Compatible with all current sensors
3. Incorporate all the newest technologies
4. Hi resolution, support Boost control, NOS, Meth Inj, COP, CNP, WBO2 and internal data logging
5. NO modifications to the current engine harness (excluding COP/CNP as an option of course...)
6. Incorporate all technologies that the Mega Squirt System already supports
7. Common interface for tuning with USB connectivity

We are on track for all of this and I'm sure the Mega Squirt Guys will surprise me with even more. The car was to be run with the prototype last week however I didn't get my Friday end ow week report. First time they missed a report but the prior reports have been promising...

I hope to have the first 10 production pieces mid next month.

Cheers,
Ron

I'm curious too here; who did the coding? Was an original ECM code de-compiled? Or a new one written from scratch?

I don't know the answer so I sent an email asking. This might be a good question to ask during their presentation at BG.
