4 button tester

**25two.stroke** · 07-13-2024, 03:31 PM

$750 obo plus shipping
Later model one, I believe it was made by control systems??? Someone may know better than me. Great tool for the 849 ECUs and the CDI racing ECUs. Checked it with a couple 849s today and a cdi box last night. Works perfectly.

That 4 button tester does not work on the 11350,a48,a63s,,I have one and it works perfect on the a6 and a13s..I talked to the person who produced these units and sold them.This unit does not have the program to read all the 11350 ecus....P.S I have owned mine for 10 to 12 yrs no issues,,,I also own a merc ddt...

Interesting. My 4 button works with the 11350 digital chip boxes to adjust the fuel trim, fire injectors, read engine sensors/RPM. And you can get an adapter for the 849 ECU. I assume you can get an adapter from this 4 button to the 11350 boxes. Again, not much you can do but read fuel trim and some testing on the injectors and read sensors. I have a DDT also but not sure where that came into this conversation.

You are correct on the 4 button merc ddt, the 1st gen 4 button had the round plug that plugged into the front of the ECU......11350...,the adapter plug went from round to a square plug for the a6 and a13...My point is this ddt forsale will only work on the a6 and a13 that you can change the program,,,via computer ,,...The Guy that made that ddt explained it to me,,,I have the adapter for my merc 4 button ddt and that will plug into this 4 button and it does not work with the 11350....If I did not already have one I would buy this ddt,,,,they are hard to come by....Ed

Yeah I bought this one a while back and used it on my 849 and cdi boxes...then I found an older version with the adapter so now I have two...don't need this one anymore. Just trying to sell it for what I paid for it. The older round ones

... I've seen people asking way too much money for them. I just paid 750 for the one I got and some people ask more. I think this is fair price for the unit I have but yes it is a slightly more limited market. My ddt doesn't have all the functions this 4b has, but I can't remember what function it doesn't have. I remember needing this to find something on the ecu that the ddt didn't tell me

There is no adapter plug for this unit this box can only read 849 boxes trust me

You are correct,as I stated in post#6 that ddt box ,,, only has a program for the A6 and A13...I uese mine all the time ,,,it is worth the money because they are hard to find.
