Re: LS1 Boost OS - Development

Please forgive me if this has been discussed before, but would it be possible to extend the Injector Flow Rate table to boost areas? I know that up to know people have been compensating by either adding more fuel or using a boost referenced regulator, but I think it would be pretty neat to give the...

Re: LS1 Boost OS - Development

So....I changed things again... I've changed how I am doing desired air/fuel ratio. I replaced power enrichment with 2 new "Desired Air/Fuel Ratio" 3D tables based on MAP and RPM. I added 2 of them to allow for different Air/Fuel ratios between E0 and E80 (Flex Fuel Enabled). I've stopped...

I thought that was what everyone did.

Re: Colorado / H3 BCM hacking

Yeah people keep trying to tell me to use the ram to watch for changes and trace it back. Never could get that to happen on the E67, as it wouldn't stay in halt, and kept resting. I think because of its separate ECU chip with some kind of watch dog. Ok It seemed like PE micro had some sort of code ...

Re: MPC56xx / PowerPC table lookup examples?

I may have fixed it. You can change the processor language for an existing project. It's irreversible, so they recommend you back up your project file before you do it. I switched from "PPC big endian 32 bit" to "PPC big endian 64 bit VLE with 32 bit addressing". The code block ...

Re: LS1 Boost OS - Development

More changes: I'm planning on making one VE table instead of 2. The main reason why I was doing two was for the P01 PCM because there isn't much unused space for new tables. For the P59 I can put all the parameters in unused address space (0x8A83E and up). Not sure if I'll want to continue to mess ...

Re: DBW throttle response

The pedal response is a lot slower in 5th and 6th gear. The calibration slows the response down.
