Hi guys, my friend that owns a '95 GST has a problem that makes us going nuts. When he tries to datalog the TPS (throttle position) always get 0% value,...
Nobody has any idea of why can the datalogger show 0% throttle position even if there's good signal on the ecu pin 84 and 5v on pin 81? Jeff, any help? ... at...
... In summary, the problem is that you are getting a reading of 0V from the ECU even when 5V is applied. Swapping the ECU with another one that is known to...
Hey thanks for the info. I see it will not be easy to diagnose. I'll tell him to try that and see. I was thinking the same thing about a possible 2nd fried...
... I'm pretty sure that shouldn't be an issue. The ECU does have its own signal tap for the TPS (as you know) and doesn't rely on a CC unit being in place....
Ok, i have news. My ecu is working well. At least i tested it with the datalogger and it reads TPS correctly. I had an idea and i tested voltage on every ecu...

Hello, my name is Chris. I believe this is my first post on here but I have been reading for a couple years now. I just installed an ostrich 2.0 romulator from...
Hi all, Say there were two identical cars, car one driving on a 0 degree day and car 2 driving on a 50 degree day. Both cars are traveling at the same speed in...

Hi everyone, I been looking at the design of the noneprom ecu, and i been wondering, can one non-eprom ecu be converted to an eprom ecu? I have a jspec...
Wasn't Todd Day working on such a Beast six or seven years ago? I seem to remember seeing a pic or two, but I want to say it was too "finicky" or some-such for...
... The difference between a non-EPROM and a EPROM ECU boils down to the port expander IC and the EPROM. To reduce the pin count on the CPU half of the address...
Im not sure but in my review of the boards, it seems as though it could work with a simple PCB constructed addon board. I may talk to craig moates about...

As Steve said, the easiest thing to do is simply set "AUX=4", if I recall, which tells the MAFT to emulate a 2G MAS, and then you don't need to change anything...
Thank you for the feedback on this one. I would like to explore the daughterboard route or better yet, i been working on a custom megasquirt pcm board that...

Is it possible that the 1100us number is a specification for the minimum amount of time that should be allowed between ON cycles to guarantee normal operation?...
... When you consider that the factory deadtime for the stock 450cc injectors at 14.0v is 648uS, the additional 432uS Jeff used gives a deadtime of 1080uS....
