Digital ECU

Exactly

..If you have a DDT,,plug it in and the temp readings should be your local area temps,,,if your temps say 225 your temp sender in ecu is bad,,,it will run rich.Check the M.A.P
sensor reading....base line from merc is 160 on 4 button and 14.6 on otc or merc with cartridge..Your ecu can be repaired if those sensors are bad.

Tested with the DDT today. The temp reading was 260. Hope to get this one fixed.

I may have a temp sensor for that ECU..I can fix it if I have the same sensor...send a pic of the back of your ECU and send to my phone...

The 849 still have chips in there prom 71 73 76 and a drag f1 champ and are interchangeable you can burn the chips for whatever prom you want can you replace them

You forgot prom75 lol

[RBT]

The 11350's have removable Chips that can be replaced as you and I both know. The 849849 A6 has a PROM (Programmable Read Only Memory) chip (its PROM code is 7119) its manufactured as blank memory then programmed but its potted and cant be removed but can be reprogrammed. The 849849 A 13 doesnt have a Potted PROM Chip. Its a ROM (Read Only memory) and is Programmed during the Manufacturing process and cant be reprogrammed.

All 849849 box's are the same, they all take PROM chips. They all have removable chips, though the chip does not influence the map only how the rev limiter come in. The map is flashed. Any and all box's can be anything you want. The newer M box isn't flashable (or is it...) but has the same issues the Brucato box has.
The new box is a giant leap forward.

RBT....Rob I am glad you saw this,,,,,was there two different builders of 849849 box....Their seems to be chips that are covered with the potting stuff and others that are clean ....their are some adjustments missing in the A13 ecu....The fuel map can be flashed as you stated ..The Map[ manifold absolute pressure] can not... The M box,,, is that the smaller A6,If it is ,,,Then it can be reprogramed by only one person,and I am pretty sure you know who that is...

The 849's built by Woodward in my opinion the quality wasn't as good as the originals 849's but the new boxes by Power performance are going to be leaps and bounds better and won't be 20 years old either lol

I agree......I thought the other builder was geirhart....I heard he had some input into brendons... new and more user friendly ECU....

Yes, control systems

Speaking of Brendan he messaged me last week and told me His ECU's should be shipping out to him this week.

[MUDSHARK]

Any idea what the price will be?

[2015Duramax]

Brendan has been telling me "next week " since first of March ….My box is shot and been waiting since everything else on my motor came from him .

[RBT]

Yes. It will destroy the used ecu market, Brendan will post it I’m sure

[RBT]

Brendan has been telling me "next week " since first of March ….My box is shot and been waiting since everything else on my motor came from him .

It will be worth it

[2015Duramax]

I was told the price would be around $1400
