Dex Lex update.
Well the car came back for service today and a boost gauge. Dex changed out the stocker plugs for Denso iridiums and the hesitation problem is gone. The car rips! Sideways and all that RWD fun stuff.
One issue: Ocassionally on start up, the engine revs very high(~3000 RPM). It won't change unless you shut it off/turn it on several times. Then it finally revs normal ~ 750-850 RPM. Any ideas?

well actually lets take a look at the Supra's profile shot. I mean I'm not baller enough to go thru wind tunnel runs but I can take an educated enough eyeball guess. I understand most consider the Supra a lift back but if you look at the rear profile of the vehicle you can see where there will be alot of lift. Just take the top of the roofline and measure how much the roofline swoops down to the rear. The swooping roofline down the rear is enough to make you wanna slap yo mama! haha ok but serious.....
The supra is actually one of the instances where a spoiler actually works very well from a design stand point. On an aircraft a wing is used to create lift. On a car if you flip it you would create neg lift. So its really about the design and angle of the wing. Most cars won't ever really test the cars limits at speeds where they'd need a spoiler so I think thats where alot of people reach their misconceptions about wings and rice. That and there's this total bandwagon about rice and all things involved w/ rice as being automatically null and void.
w/ the stock roof level wing you get 66lbs of downforce at 90mph. Now think of most Supra's owners.... 90mph isn't much at all for a Supra owner. As you are reaching top speeds down the track would you be willing to trade 2-3 mph and a bit more drag for upwards of 200 more lbs of stability. So basically what you are looking for is the best comprimise of downforce vs drag. And for most of us we even factor in the pure aesthetics of it. Most people who try and knock it right off the bat really have no clue. They are adding on countless mods that serve them no use for their purposes but hey... to each their own.
And then you have some weirdo's out there who just might panel the bottom side smooth and get wider tires!

Going HKS F-Con soon. I will update. This unit seems to be flawless and works great with our cars. Or any OBD2 cars for that matter. Piggy-back units will never work great... They will work, but the relearning issues are very fustrating.
Hopefully the guy coming down from GA knows what he's doing..

So for those that are running the Aristo vvti ECU. Did your body harness ECU plugs plug right in as well?
I'm trying to do an Aristo swap on my '02 IS300. The body harness ECU plugs are completely different and I don't have the pinout for the Aristo harness on for the body side.. I also have an Aristo ECU w/ immobilizer so that is not an option unless I can source a non-immobilizer Aristo ECU.

No, I'm running a s-afc2 for now. I'm still enjoying mu US spec twins.. I just had a horrible time with that shop. I don't like to trash anyone so I never posted about it but lets just say I wouldn't step one foot anywhere near MTR again...I was just wishing Burgandygs good luck...
