Anybody seen or used this lap top based diagnostic system?

[Ascension]

This was suggested to me off another site and looks very interesting if it works. Has anybody here tried to use this system? Supposedly it would connect to both my E 420 and the 300 TE with the optional adapters and be a huge step up from using a blink if it works as advertised.

HFM Scan now works on 500E'S!! | De-Coding

For everyone with a LH Mercedes this might be of interest- Early on after buying the 500E I contacted Mike K (HFM Scan) and enquired if his software would read a 500E Live Data. Long story short I have been assisting Mike with Data from my 500E over the past couple of months and he has been...

Not sure where you got the other information, but per their web site, I do not believe it will work with CIS-E-based systems (M103) and only supports HFM-based (M104, M111) and some LH-based (M119) systems.

For M103 and M117 generation engines, you can only use a home-made straight blink-code reader (or a compatible system such as the Trisco PalmScan or MB STAR C3 with compatible cables) to pull codes.

M103 / CIS-E Duty Cycle readings require a digital multi-meter with duty-cycle capability, which attaches to the round black connector on the inner driver's fender-wall.

Or, you could use the rare-as-hen's-teeth Bosch KDJE-P 600 tester, which per the photos below plugs right into the X/11 connector on the fender.

That is for HFM systems only. Won't work with either your LH-SFI E420, nor your CIS 300TE.

HFM Scan can provide limited data for the E420, from the LH module only (nothing else). More info at the threads below, and Gerry's link above.

HFM scan for 1995 E320 (M104 engine) | Off-Topic Discussions

I recently saw the HFM scan in operation in North Carolina. The gentleman has a USB cable attached to an OBD harness and the software on his computer. He was able to get detailed real-time information about his engine (1994 E 320) Does anyone have a detailed write-up on how to set up this HFM...

Full diagnostics on the E420 requires an SDS with HHT-Win. Diagnostics from the CIS system cannot be done via scanner, it's all old-skool blinks and on/off ratios. (Which is one of many reasons I won't own a car with CIS.)

Thanks for that info. Have a good blink but it would be nice to be able to get real time data on both cars for things like the O2 sensor function ect. Had never seen this system and wondered if it was worth looking into.
Finding out about the CIS diagnostics and it's a real PITA to get any credible info on how to do it.
Thanks for the info on this system guys.

CIS-E diagnostics are fairly primitive, at best (nod to the @gsxr on this statement). There is NO WAY to get any sort of real-time data on a CIS-E system other than the on/off ratio that I mentioned, accessible via the X/11 connector on the inner fender-well. But this is not diagnostic information, rather mixture and emissions-related.

On CIS-E, all the "E" capability does is use the computer to take signals in from a few different sensors and generate a control signal that goes to the EHA to fine-meter fuel based on current operating conditions. These inputs for the CIS-E computer include the throttle-body switch position; engine RPM; starting signal; engine temp sensor; air pressure; and air-fuel mixture (O2 sensor).

The blink codes that CIS-E has on MBs is pretty simple. There are reference tables for it all over the internet. Remember this was a full-on mechanical injection system that was designed in the early 1970s and very very slightly computer enhanced in the early 1980s with the CIS-"E" system.

Basically the CIS-E blink codes just refer to failed components, that is all.

True real-time data was not available until the LH system debuted in 1991 for the E500E models, and then spread to other engines/chassis from there. Even the LH real-time data is pretty crude compared to the follow-on ME and later systems.

this makes the M117 very simple.... Glad I got one.
