I have STI injectors, Supra Fuel Pump, Fuel Pressure Regulator, MRT Intake, MRT FMIC, HKS Carbon Titanium Exhaust, LINK ECU I have an ok hadle on how to tune the chip but i just want to make sure i don't mess anything up. I still have a few problems any input will help.

When i start the car i have to turn the key twice to get it started and hold it for quite awhile.

Second, I am using a lot of gas (is that just because of the fuel pump? What Gas Mileage are you getting?)

Lastly, The motor gets very hot to the touch. The link reads only about 90-94 degrees on average but the motor just seems much hotter than normal. What can i do to fix these problems or is this normal?

Hey ... while I don't have the upgraded pump and injectors ...

here are my comments

1. wait for the pump to pressurize ... you can hear it. We've talked about this before. Turn the key to the first position ... then wait. Then start the car.

2. I just got 320 miles on 1 tank with a autox in there as well. thats about 24 MPG> i have a MPG and Link thread around here somenwhere ... though not many seem to be interested in saving gas

3. heat wrap your DP and turbo

To fix the car starting issue, turn the key on, but don't start for 5 or 10 seconds to give the Link time to boot. Should start fairly quickly then.

Some on the board are getting decent mileage, but I'm definitely not, because I'm running pig rich anytime there's boost to keep my knk values down. I believe this is due to some combination of at least 3 factors - crappy 91 octane CA gas, fuel hitting the pistons, and/or the turbo (FP upgraded) pushing hot air into the system. I will see if the third is a factor tomorrow when I pick my car up from Suby Specialties, as they're installing my MRT FMIC today and tomorrow and I should get significantly better cooling of the intake air over the stock IC. Would have done it myself, but I'm lacking a plasma cutter or the patience to go through a hundred cutting disks with my angle grinder.

As for the hot engine issue, I dunno, but if your coolant temps aren't getting any higher, it could just be your imagination.

SFastWRX,
Just saw yer ride at SS that MRT FMIC is all business...Steve was busy working that bumper beam:devil: can't wait to see how it turns out.

Me too, Areg! Thanks for the compliment on my ride. Brett M and crew make a really nice piece. I just talked to Steve a little while ago, sounds like he's having "fun" hacking away on that beam. ;) Hopefully the reduced pressure drop will let the turbo breathe just a bit easier and the larger core will remove enough heat that I'll be able to take some fuel out of rows 7 & 8 on my link when it's done. If not, I may have to consider upgrading the turbo again to something with a little bigger exhaust housing.

Thank you for the input. If anyone else has any suggestions i would love to hear them.

THanks
