Evo X upgrades

[mlomker]

I did go up to BIR but I only got 8 laps in. It got to the point where it was misfiring even at high rpm and I just wasn't interested in abusing the motor.

Sweetness. Sadly though, you get used to the power after a bit. Lucky for you it just keeps going back for more, haha.


I believe it! For the sake of expediency, I requested that Shane polish up my current tune and leave the power level where it is at for now. I dropped it back off at DB on the way home.

The good news is that the car feels awesome. The suspension setup is confidence-inspiring on the track and the tires didn't even squawk at the pace I was running (admittedly slow). It's something that I can grow into for the rest of the Summer...can turn up the wick later.

^That sounds like a good plan.

Sorry about the misfires man :( Did you try swapping in the stock coils?

Stock coils and a set of HKS one-step colder plugs. I called around and none of the local Mitsu dealers had a set of new stock plugs in stock on Saturday.

The car never misfired when I was on the DW1000 injectors and the old tune. The misfires occur around 3k rpm so it shouldn't even be boost-related. You let off the gas approaching a turn and then go part-throttle to accelerate through it and pop.

I'm hoping Shane can iron the issues out with a few more hours on the dyno. If not then different injectors are going in. We're watering a plant with a fire hose. DW needs to release the 1300's that they have in beta testing. They'd be ideal.

You can't just go to Napa or O'Rielly's for spark plugs?

IX's and X's use specialty Iridium plugs that can be tough to find locally (X's especially). They're expensive, but they also last a long time (I swapped out my stock plugs at 46k miles and they still had plenty of life left in them).

You could talk to Chris at MAP and see if he could get you those DW1200's that I was going to test for them.

Since I won't need them I am sure they are still looking for someone to test them, plus you would get them for a smoking deal ;)

For your levels the dw1000's should be fine anyway, I ran mine up to 420whp on Shanes dyno, probably 430whp with normal size tires/rims and still had a bit left.

If nothing else, at the power level you are at you could toss the 1000's back in for a while and just have shane tune you on them. Then you have a good solid car, and can swap in bigger injectors when you know there is a product that will work for you. Misfires are bad bad bad at this power level.

That's a definite possibility since I know they run perfectly. I have them at home instead of DB but I think I'll just give Shane a crack at getting the ID's to work.

Yeah but I like to plan for the future and not satisfice. The math gets tough not matter how you go about it...selling old injectors, buying new injectors, paying Shane by the hour, etc.

I talked to a guy with the new DW1500's and his symptoms are identical to mine (as far as warm starting, etc). The misfiring needs to be fixed but hard to say what others issues might remain. The DW1300's should be the perfect size if they tune like the 1000's...getting a set is definitely on the option list.

IX's and X's use specialty Iridium plugs that can be tough to find locally (X's especially).

Plugs on the X are stupid. $18/ea for stockers ($22+ for aftermarket). I don't think it's the problem anyway but it was Shane's suggestion to try new plugs.

Yea misfires are the suck...


I ordered plugs from AMS and got them in like 2-3 days. No dealers stock them, they all have to order them and they are very pricey.
