ultimate is double of the price of blue... but the difference between these 2 only minimal... even using same 16x16 table but the difference only on 0.5% and 1% incremental which giving ultimate better in fine tuning... if u have the budget u can go for ultimate... or else u can take blue is more than enough....
why spent a standalone cost but running on piggy? might as well use piggy though...
u can also refer to my posting at the other thread; management for campro 1.6...
Hmm...
EMB
-AFR Mapping direct alteration of the stock Mapping
-MAP sensor is only to read anything beyond the stock MAP/MAF sensor of the OEM
-Can't incorperation Wideband O2 for autotunning
-1 Mapping storage at a time
-No rev limit change(Some did it with the injection harness with signal from the external injectors)
-No data loggin within the EMB
-No for fun features
EMU
-AFR Mapping can be independant. Meaning to say, U key in the targetted AFR instead of +/-
-MAP can replace the OEM MAP/MAF. The MAP sensor react directly to the Mapping of the EMU.
-Able to autotune when plonk in Wideband O2 sensor
-2 Mapping storage at a time-change with a push button
-Can change rev limit to higher/lower - mapping based on EMU, not stock ECU.
-Able to datalog with the EMU
-Launch control
Just to share some of the difference that justify the price.
