revo,jabba or apr??
WhiteHartMart:
Have to say that explanation was interesting reading - APR looking attractive for me too - dealers down here just seem sooooo anti mods :sad1:

Have to say thats added a bit more data to my memory banks thanks Keith :happy2:
I thought it was switched not reflashed each time!
which brings on my questions.........
1.When I select std map it takes 10 seconds at most to select the map via the cruise.
So why does it take longer when 'flashing' at Awesome etc? (or is it always 'seconds' to flash the ECU code?)
2. Surely switching between maps would have been 'safer' ?
I guess youve chosen this method so it is OE in stock mode but is this reliable and safe?
The ecu memory will also have a flash limit for the number of times you can do this, any idea what it is?
(I assuming Id have to switch to and from stock each day for 10yrs + to even get to this limit???)

1. The first step of DPP is to completely read out your entire ecu and our server compares your oem binary to other oem binaries' and verifies the integrity of your ecu. This takes about 2-3 minutes depending on ecu.
Once the binary is read and verified, our DPP server compiles our performance data with the remaining maps of your oem code that we don't change like start up maps, some part throttle mapping, etc.
When the compilation is complete, another 2-3 minutes, your entire ecu is reflashed.
Add in another 3-5 minutes for internet data transfer and any que in the DPP servers from others flashing and there is your 10-15 minutes of actual DPP flash time. The installer spends another 10-15 minutes entering in your customer data, setting up the flash and using a diagnostic tool to verify the flash, etc.
When our engineers use an internal flashing tool that is much like the EMCS works internal to the ecu, we only flash the calibration sectors of the ecu which is only a portion of the 2mb, don't have to compile the total OEM binary, don't have to wait for any internet or DPP ques, it takes about 10-15 seconds.
2. There are several flashing counters and other protocols in the ecu that can limit the number of flashes or alert the oem dealership to more flashes than the ecu should have. Part of reading your oem binary is to determine the number of flashes your ecu has seen prior to coming to us. This allows us to rewrite your flash counters back to their same number of flashes before you came to see us so noone will know your ecu has been flashed off of the OEM dealership network. EMCS doesn't have to worry about the counters as it flashes the internal memory of the ecu in a way that the counters aren't designed to record as a flash.
Internal ECU flashing is a more elegant and powerful solution and keeps the OEM code exactly OEM. Its a more advanced way of doing it and also provides some code integrity and security protocols. Almost every tuners' code can be stolen and from what I understand our product is more secure than most and we go to great lengths to insure it stays that way and internal ecu flashing helps with that as well.

really appreciate you taking the time to respond Keith :happy2:
