The only way to absolutely know that 87 is fine is to do some datalogging, if you're concerned about knock you can bump up to 89, 91 is overdoing it and 93/94 is just pissing money away.

 

icic, thanks for the help!

But what about the WORKS ECU flash, it asks what octane you want them to tune for. Does that mean if I get my ECU flash by them for 91 octane, then it is okay to run 91 in the long run and not harm the engine?

 

The reason they ask what octane you want is because they can go more aggressive or less aggressive with the timing depending on your own wants/needs. Higher octane allows for more aggressive timing which in turn makes more power. If you are tuned to run 91 octane, it's perfectly safe.

 

Yeah running higher octane when your car doesn't exactly need it is pretty pointless. And what amby has stated is true. Higher octane gas can help with engine knock and pinging. Read your car manual. If it prefers higher octane i would follow through. If not using the middle gas is okay. I would prefer using the middle number.

 

Can anyone tell me what exactly is performed by the technician if i get my car-- Lancer GTS tuned? I thought tuning involves altering the ECU code....and yet so far only Works provides a ECU flash. Even if i got a flash how would i know if it's the best settings for my car? ( They would only have my mailed-in ECU, not my car)

 

I presume the WORKS reflash is a generic reflash, not specific. In order to get the most out of the car, you'd need to get it road/dyno tuned.

 

I am sure you guys are gonna love this. I have a few production peices on order now that we have finished the dynoes and nights of 100 mph pulls down the highway. This is the only way to go if you have mods and are in the process of adding more and more things. IT will adjust with it. Just like a piggy that will always be tuned, tunable (custom) and able to be romoved. Flash is just a one time thing and cannot be changed as you add more mods etc....

^^ Very well said.

 

is it possible to have a V2 piggy that perhaps combines with this new advance timing thing that is plug and play also?

 

Are you talking about combining the piggyback with the flash?

 

yes you will use the piggy+plug and play

 

i wasn't sure if this new device is a stand alone product or it requires the piggyback. i would get a piggyback if i didn't have to splice the wires.

 

+1

 

THis does not replace a piggy but it is a step in the "PIGGY DIRECTION" but it just plugs in.

ROAD/RACE

 

so it is possible to just have this product, no other mods? would that produce any more power? How much will it be and when can we buy it on your website??
