Re: Crash course me on EEC-IV A3M
I see the GUFB.xdf, I also found A3M.bin's online. I've also added 8k of blank data in front of the 56k A3m bin to make it a 64kb file and align the table addresses to match the GUFB.xdf, do I need to remove the 8k of blank data on a modified .bin before loading the .bin to the quarterhorse to run o...

Crash course for GM TPI
Hey guys, is there an online tutorial or guide for navigating the GM TPI ecm's, .xdf and .bins? I am familiar with OBD1 BMW Motronic chip tuning. I'm familiar with carb & dist tuning small block chevies as well as modifying OBDII GM by way of HPtuners. But this is my first OBD1 GM. https://previ...

Everything worked out great until the system went into WOT values. At WOT the DME still used ignition values from part throttle map as planned, however the fueling stopped cell hit tracing from PT fuel table during WOT protocol and with the throttle open the engine did indeed act like a fuel cut and...

It's been brought to my attention that the M3.x.x can indeed live data from diag port. You need an old Windows xp computer with an rs232 serial port. And you need the Tiny ADS interface.

I do agree I can watch mine switch out of fuel cut around 1500rpm and there very well might be a single byte or two that controls that RPM point. If so I would imagine it's in the front of the code where the Rev limit, Speed limit, Injector Constant...etc. are located. I have a feeling Olafu would b...

I'm throwing this out there as an idea to investigate, I don't know for certain. But...perhaps the answer to your engine overrun/decel/fuel cut is in those TPS threshold tables. We already know about the Idle to Part Throttle threshold and the Part Throttle to WOT threshold, but their appear to be s...

M3.3 waste spark
Hey guys, can any confirm or deny if the Motronic M3.3 goes into waste spark when cam sensor is disconnected?
I've heard about the injectors going into batch fire and was wondering if ignition also went into waste spark. Thank you!

What is the TPS function actually used for? When I tried it it was not actually traced? Is it reserved for the limp map?

bosch 60-2 trigger wheels - 4 data points per tooth, 60 teeth counting both leading and trailing edge = 120 edges. so 120 edges * 4 datas points means 480 points per rotation. 360/480 = 0.75 deg per data point.
