Ok so I have a 2006 is350, full tien suspension, full exhaust, and a k&n intake, with hks grounding kit. Now with that out of the way, my next step was to tune it but was told by some local guys it can't be done... Is this true or can i get it done? Is there a hand held tuner, or shops on the Oklahoma/Texas area?

 

no tune for the IS

 

sorry buddy. ECU is encrypted and there's no way to tune the 2IS.

 

You can use a piggyback system like an HKS F-Con Pro or a MAPECU3... but you're not going to see much gains from it (5-10 hp)

If you bought the ISx50 to mod for power you bought the wrong car.

 

U need PPE header+ 15Rrwhp to complete the list. There is one group Tuner in TX are trying tuning the ISF with good progress so far , but still waiting for the final result so stay tune....

 

^Are the ISF and 2IS ECUs similar in layout and design?

 

Damn see thats what I thought... Thanks for all the replies. I'm not trying to run 10's just want the most out of that I can get. But yea it will be nice if that place in Texas could pull it off. But how does it work if you start spraying or boosting? Does the computer just adjust accordingly?

 

Up to about 5 psi, sure.

Which is about as high as anyone has managed to run for long on the 12:1 compression engines these cars come with.

The one exception I'm aware of is HKS350, who ran an F-Con Pro to manage 7 psi, and a guy in Greece running a MAPECU3 on his 250 for a similar amount of boost.


After that fueling and other things become major limits (in addition to the high compression limitations)

 

O ok, what about like a aem ecu? Has anyone used one? I have seen them for a few other cars
