Good day all. I have been tuning a few 2ZZ-GE engines using the emu black v3 with great success however, i find the vvt table size is very limiting in regards to how much power you can extract on the lift area. I dont know if i am in the right area to submit a request but can we have an option in the software to allow us to choose between a 10x10, 12x12, 14x14, 18x18 and 20x20 in the general options tab for fuel, ignition, vvt cam 1 and cam 2 control? like a checkbox area to allow expansion where necessary? Currently the vvt table is a 10x10, it would be awesome if it was a 10x20 to give more range of control OR separate the locked y and x axis between cam 1 angle 1 and 2 tables so you can configure the RPMS on cam angle 2 table differently when using the table switch method? FuelTech uses a 16x16 and works well however i am already fully invested in to EMU Black on 5 cars and would love if an adjustment option could be implemented on the next patch vs forcing a need for a different ecu?
Also is it possible to have a 1zz/2zz-ge cam preset profile added for simpicity? currently we use an n-1 with certain filters etc and it works fine, however if there are known better options available with more precision, can a preset option be implemented? vw 1.8 preset works same or similar to the n-1 option for the 2zzge with out changing the cam offset but i know it uses a different cam reading window, slightly wider.
According tables size it is not possible.
We made a lot optimisation tonfit everything in RAM and there is virtually no memory left.
You can play with table brake points to make it optimal.
Accoriding CAM trigger, please send the scope Inwill advice the setup. V3 has very felxible CAM setup
I have a 2zz turbo setup running very well on emu black. The vvt table breakpoints are really a non issue. I’d say two reasons.
- cam angle response time just isn’t that quick. Making adjustments in a 20x20 table vs a 10x10 table might not even translate to actually hitting the target in the table. The 2zz has a very harsh switchover right when the high cam turns on, the ideal position is only a theoretical ideal, I’d guess even in stock trim gears 1-3 never hit the target across that point during a full throttle acceleration.
- the real world power to be gained from slight adjustments anywhere in the cam table is hardly noticeable, probably within margin of error on some dynos even. Adding a break point between two optimized positions is well into the territory of diminishing returns.
Also, emu black will always have a leg up on the current ft offerings regardless of table size because of the easily customizable can messaging.
Also, worth noting. I moved to single table on all my variable cam lift setup. I know people get used to having a large number of tables between high cam and low cam because the k pro and some others have it that way but in the real world this doesn’t really bring much benefit and requires keeping track of more tables. The extra tables can then be used for flex fuel blend which brings a large performance benefit, much larger than small vvt and fuel tweaks across the cam switch point.
Something to consider as you dial in your 2zz
