Dear All,

As per title, is it advisable to delete MAF sensor and use 3 BAR MAP sensor to handle the 1JZGTE VVTI. What i've gathered is with MAP sensor, we can manage the AFR more accurately and tuning for more powaaaahhh will be easier in future.

I have been offered of a Greddy Emanage Blue + Boost Pressure Sensor (not sure same with MAP sensor or not) to get the job done. Before i get into wild things like this, please share some inputs.

Thanks,
Ken

power yes, but im not sure if altitude will have any affect.

Anyway, I wont go for emanage, straight go for standalone. Can your ecu remap?
No the ECU can’t be remapped, i don’t want any complicated job so i am opting for piggyback only. I want to optmize the AFR and possibly increase a little boost on turbo, target HP is 350 at the crank. However some guys said it’s not needed to convert to MAP if i am not boosting over 500hp.

Thanks,
Ken

tuning with map sensor alone means going for speed density tuning...

and the fact it will be handled by emanage blue.. that is notorious for being faulty/clone or lost its tune out of nowhere.....

i suggest u keep the stock ecu tune...unless u were going with higher and better standalone ecu....


and with the nature of tuner in malaysia way of tuning, u can expect losing on fuel consumption, smooth driving and likely smooth idling that is on stock ecu....


trust me...if u were not going to mod the engine all out, keeping it stock tune by stock ecu is a much better option for road car.....

I am not looking at crazy power upgrades (YET) but wanted to optimize the AFR. I had modified all the, exhaust, downpipe, intake and intercooler pipings when converting the engine in a E46 chassis and i am pretty the air flow measurement is slightly off compare to stock tubes. My gut feelings telling me that the current engine performance is not optimal yet. Idling may be stable but during drive, the acceleration is kinda off as i am expecting even stronger pull.

I have 2 options now, Unichip Q and Emanage Blue, obviously Emanage blue is not everybody's favorite so i will pass on that. What do you guys think of Unichip ? Last time there was this RS Tune used to tune Unichip in Puchong.

Thanks,
Ken

im not saying that u cant use emanage blue... just that device capability not worth going to map sensor based...unless the tuner is definately able to smooth things out on every driving occasion...

Hey you think we could meet up one day and let me sit in your car for comparisons sake? You're running on stock turbo right?

Yup sure, however weekends only i am available.

Edit: still using stock turbo and manifold, only modified down pipe.

Thanks,

If my target is 350whp, without going MAP conversion, can the emanage BLUE able to do it?

Thanks,

I doubt you can get that number without a turbo upgrade. My setup had a single large turbo standalone ECU setup to get 360whp with lots of supporting mods (top feed injectors, fuel pump upgrade, injector upgrade, etc etc)

My plan is to hi-flow the CT15B, standard boost at 0.9 bar, scramble boost at 1.4 bar to get to 350whp when required. The modder’s suggestion to me, larger fuel injector, better ignition, spark plugs, after market BOV to get to that numbers.

Feasible ?

Thanks,
Ken
