I am writing software interfacing our dyno to the V2 and it would be very convenient if I could test the software at my desk (where my development environment is) then at the vehicle (which is a pain...

So how is dynamic spark done? Is this available for say the E-37 and E-38 computer or is it only for the old LS1 stuff? Is there an OBDII command to change timing and assuming there is, why (could...

Paul, I'm not interested in LS1 controllers. They are too old. I'm only interested in current technology and in alternative fuels. All of the tuning that I am doing is on Ethanol, Methanol, E-85...

Is timing advance available any other way? Does the current scanner software support live timing changes for a particular cell or as an offset to the timing tables? What about throttle position? I...

Perfect! I would very much appreciate this. I have extensive programming experience.

Thanks,

Sam

Power produced per fuel used will vary based on spark timing. Optimal spark occurs when power produced is maximized as spark timing is varied.

This interface doesn't depend on the dyno used. It only requires polling the RS-232 port on the scan tool to access the data. You can send a "D" frame to get a list of the current PIDs being...

This is certainly a step in the right direction and I will go ahead and implement an interface to the dyno software, but the frame rate is very low with rs-232 and it requires an rs-232 interface. ...

I am writing control software for a dyno that we have just installed. The problem is that most dynos are really just designed to do wide open throttle tuning and frankly pathetic software and...

Thanks, but I the very reason I bought the engine was to gain insight into DOD and Variable Valve Timing. I am an engineer and this is for work. I did purchase an E-38. Now waiting on a harness.

Off the methanol stuff for a while.

I have a couple of questions for those that have done it before. I am getting ready to do a conversion of a 1986 Corvette (C4) to the following: 2010 L92...

It's always easier to spend someone else's money, isn't it. :-)

...and just what constitutes a professional here?

He obviously has access to an EFILive tuner. He just needs to watch his...

Nate, your concern is valid, but in my experience I have never needed to upgrade injectors in a stock application. Usually, there is PLENTY of headroom.

Try it and just look and monitor your...

I am putting together an L92 Engine and would like to get some opinions on the best ECM to support:

1. Flex fuel operation.
2. Variable Valve Timing.
3. Displacement on Demand.

I was...

Boy, no kidding. I am 50. The 555 was old when I was a kid! I wouldn't use a 555 for anything anymore.

I completely agree about the AVRs. They are awesome. I just wish that documentation from...

I have yet to find anyone that has confirmed that the flex parameters actually enable flex fuel operation. So far I have confirmed that people can shut it off, but I know of no one that has turned...

Bill, I just want to make sure that while there has been "progress", the car still doesn't start. The fuel is clearly being disabled (most likely the injectors).

The car attempts to start,...

I am not sure if once again, I am experiencing the same problems I have been having with my software (Such as the VATS Patch not working) or if I am doing something wrong. After sending Andrew my...

Thanks, Taz

I've made the switch on all the files and saved them in the new format. Looking forward to V8 being released. It looks like a significant improvement.

Sam

Sorry, I didn't answer one of your questions. Yes, the full flash icon is fully greyed. We can only fully flash by saving as a ctd file and then bringing up V8 and using that to write the file. ...

Yes, believe me I know the difference. I have written USB interface drivers, both low level (micro-controller side) and high level (operating system side) (HID, CDC, Storage, etc). It is absolutely...

Here is one possibility.

I brought up the licensing data on the FlashScan and found that both the serial number and the license number are the same. Could this be the problem?

Yes, there is clearly communication taking place. Best guess is that the firmware is responding with the wrong data. I could try sniffing the data traffic over the USB bus during this boot...

The OS is 12635399. It is one of the supported OS's.

I tried the Holden file... No good. The VATS OS Patch options don't come up.

Andrew (from support) spent some time connected remotely...

I have done that. The V2 is plugged in prior to my opening the file. No tune file is open and still no joy. The options don't appear.

Interestingly, I spent a few hours earlier trying to get...
