Electronic Boost Controllers

[George Elliott]

I would recommend aumotive route to anyone going stand alone.

Sounds great......to think we have a 991 era replacement for the OE Bosch Motronic pigs-ear-logic version ECU. Thx for posting George 944t

an electronic boost controller may be progrmmable allowing different boost profiles

fair point Simon, a genuine benefit provided the Engine Management is clever enough to manage overboost such as on a 997TT or gear related boost limits. I voted MBC as my Engine Management is similarly basic. If Santa brings me an Augment ECU like T3rra runs, I would agree I need a solenoid operated boost control. George 944t

I asked Tom about boost control last year and he said that he could include it.

Awe, poor Motronic! I love the motronic, the real shame is that it spends a lot of time performing calculations to make all it's code and maps fit in a relatively small space, which is aggravated by it having to store numerous maps and tables which are never used, or for international use. I good example is the airflow meter transfer tables, and the calculations used to turn three tables into a fine curve which would have taken up a little more rom space if they were pre-loaded, and it has to do this on the fly, hundreds of times per second, which if they had chopped out some of the more useless maps which were provisioned just to avoid recalling multiple ECU's if they discovered an issue in the mapping.. Once you chop these out, you have more space for code for the transfer function to be one large table, and free up loads of cpu cycles to do something more interesting or precise instead. And this is just one example. I guess I am just autistic and just hate to right off a component until you really have maxed out the original items potential.. But also I think I am really attached to the fact that I can get it to do anything I want very quickly because I know it inside and out. Toms ECU is cool, really cool... I just wish I could have it and have access to it on a software level. I also think Toms ECU will one day be essential for keeping these cars on the road once used DME's dry up... A good example is I have 3 KLR's in my lab office which can't be repaired.. Usually I find the faults in them to be down to one capacitor, one resistor or one voltage regulator which have reached the end of their life, or have been burnt out through another fault... However, there are a couple of components in there which just are not available, unless you were to build a daughter board to replace them. Which no one will do while they can be had cheaply on ebay, but also no one will do once the ebay ones are not available and the demand might only be one a year... But that one a year is another 944 which can't be fixed. Toms solution, looking and acting OEM actually provides a future for these cars, and could be used in a stealth mode with a standard looking engine bay, passenger footwell and standard power levels to keep a true classic going. And to be honest, I think the DME and KLR are probably the only two parts of a 944 that could not be reproduced easily other than through the efforts of Tom. So, well done Tom, I really am a fan of your product. (And before anyone asks why I am bigging him up, No, I don't sell his product, have not installed his product, although would like to, so no other motive!)
