Steve said.. if you want to add race fuel for higher boost... he can tune it in with the current tune, and just change the map so its adjusted for the race fuel at high boost.

But if you want two seperate maps, you'll need a datalogit of your own to change them, and you'll have to pay the $150/h rate.

At least that is my understanding.

 

....I have a datalogit.... i'm currently tuned by myself... pretty damn nice imho but i've never been in a "well tuned rx7" so i have nothing to compare to. what do you mean 150/h rate? is that with the 350? w/o it?



So.... he can tune for race gas without race gas???

 

I asked steve for 3 tunes. 1 for pump, 1 for pump + methanol, 1 for c16 race fuel. Steve said, in order to be fair to the other members who are paying $350 for one tune, he would have to charge me the $150 per hour rate in order to get 3 seperate tunes. It wouldn't be fair for me to pay $350 and get 3 tunes and everyone else only gets 1. So the $150/h rate makes that possible.




No, he can't tune for racefuel without racefuel. Basically, you'd do pump up to your desired boost level. Then, you'd drain your tank completely.. and run the pump so it dumps all the old 91 octane out. Then load in X amount of gallons of Race fuel (you'd probably figure a minimum of 10 gallons to be safe). Then get back on the dyno/road and run the tune under the higher boost levels. Then, use your boost controller to limit your boost for pump, and when you want to up the boost.. make sure you have a tank of race fuel and up the boost controller.

 

Actually I heard that doesn't work so well with the Power FC when you tune for two different octanes on one map. The reason being is that the map will get "confused" between the lower and higher areas of boost causing you to run too rich or too lean.

 

I'm not the best at tuning(and have no experience with racefuel.) but... if u have c16 in and you tune it off the pump map wouldn't you be very rich while building boost because it will use the racefuel like pumpgas at the areas below your high boost settings? so wouldn't I be making less then max hp? From my understanding, with racefuel you need to tune the entire map again.

Steve says it can be done, XS has also told me the same.. I believe it to be true =)

 

**** xs.. steve is good and he is cheap too!!! no comparison, hands down.. i cant beliexe xs is still in bussiness!!
you cant watch them dyno tune your car,(xs) and your paying them money? thats a bunch of bull!! why?

 

Yeah I am on the list for STeve's tune here at the end of the month. I just have to get the KAI and the T2 diff installed and done before he gets here =./

 

Actually, they let me watch them dyno tune my car, although it's not something a lot of you will want to see. The car is on the dyno with an open wastegate super loud getting run on, and everytime your like "hope that motor will stay together" haha

 

My brother took his car to XS and they tuned it after they tried to BS the both of us for about an hour with "what it needed". The car made 340 rwhp...and then grenaded about 6 months later.

I fixed the engine and Steve tuned it. The car made 360 rwhp plus but the clutch was slipping so there was more in it. Steve even riched the A/F's and the car has been working just fine.

Stay away from the Mickey Mouse shop and let Steve do it.

xs is way too expensive. Steve is so much better and will let u watch. whats the secret that xs doesnt want u to no, humn.

 

There isn't any voodoo in tuning. I've watched Trevor tune and he did a pretty good job.. and it's simple. I just don't have the money to dish out on a dyno so I can teach myself... lol.

The reason XS doesn't let you watch is all cause of liability... esp in California... people will sue over a stubbed toe that they got in your shop... lol.
