Leave the SST alone unless you plan on tracking it, in which case get the SSP cooler only. You WILL overheat it without the SSP cooler on the track. I have been running a 100 octane race tune, about 375 whp, 350tq for two years and over 25 track days on stock clutches and SSP cooler. I'm about to install an EF3 and have complete faith the stock cluches will work just fine. (just turning back the torque)
Everyone is always quick to suggest replacing the clutches. I was given some advice a while back about the SST I think more should follow: don't crack that thing open until you absolutely have to. change the fluid and filter ASAP if you haven't already and be done with it. I'm in IL too, I can show you how. just like changing your engine oil, except you have to measure exactly how much you drain and put that same about back in.

 

No more posts by people who have no clue what the difference is between a wheel-speed sensor and a TPMS sensor, please.

No more posts claiming that RFP1s will somehow cause problems for the wheel-speed sensors, please.

No more posts claiming that small changes in the diameter of all four tires will cause any problem at all, please.

Thanks.

 

People on this site have said that Mitsubishi doesn't check the ecu for tampering. Now this is shocking and bad news. There goes the upgrades I was looking to do this summer. Can anyone else confirm this for sure.

 

Really?? I have no clue what the difference is between them are you serious? Do I need to post pics of evidence from my experience of this occurring & confirming that it was the wheel speed sensor? I never said this will cause it to all of the evos did I? I said it "can" happen because I've seen it happen many times even on my own MR! If this haven't happened to anyone else then great for them! There was even a thread about it on the forums a while back! No need to scare everyone to not buy aftermarket wheels, I'm just saying it can happen! Just like if someone posted a problem with the sst that maybe just a few people had are you going to say not to post any more topics on the issue of the sst? I'm just trying to keep you guys trouble free.

 

What I am saying about the ecu tampering is that, if your car were to ever have some mechanical or electrical failure & I mean a pretty severe case, they will check the ecu & if they see that the remap could have lead to the problem then they can very well void your warranty. In any other reason you bring it in for reg maintenance then no they will not check your ecu for remapping or tampering.

 

Well obviously they wouldnt revise my ECU if I'm going for a simple oil change. But if I go for a check engine light for faulty VSS and I reset the ECU to stock your saying they can see if I flashed the ecu to deny coverage?

If it happens to one evo wouldn't it happen to all if not most since it is the same exact car with almost exactly the same parts. What your saying is correct from cars I've seen other than evo. Hell, one time I got a flat on my 06 si and had the tire replaced. Freaking light would never want to come off. Most likely due to TMP sensor broke in the process of driving with the flat.

 

Trust me I know at first it sounded weird at first about the whole wheel speed sensor issue, but modern cars now a days are filled with very sensitive sensors. On my older cars I would never have issues changing tire sizes or wheels even if it was a drastic change from OEM. But those 235/40 is stead of 245/40 on the EVO did make a diff apparently and caused what I had discussed. Well in your case of the of your SI sure the sensor could have broken or something wrong in the circuit, but you should have been able to reprogram the TPMS if the sensor didn't break off.

 

So, I guess you haven't seen the directive from Corporate that tells dealers to check for a reflashed ECU on any and all Evo Xs that are brought in for any reason.

 

Maybe your problem is not using paragraph breaks. Maybe much of the problem could be reduced if you wrote separate paragraphs on wheel-speed sensors and TPMS, since they have absolutely nothing in common on our cars. Yes, there are cars that use wheel speeds to determine tire pressure, but we don't drive that kind of car.

As to the first part of the above, please explain how the wheels and/or tires that you put on an Evo X has any effect at all on the operation of the wheel-speed sensors. Yes, if you mis-match the diameters across the four tires, you can end up throwing a code, but this isn't because the wheel-speed sensors have stopped working or were in any way affected; it's because the ASC, ACD, and AYC ECUs are receiving contradictory input.

 

woah? I never said that the wheel speed sensors and a TPMS are anything alike ok, never said that. They both do different tasks. And I never said that the TPMS were giving any problems they were working just fine!

I never got a code from the wheel speed sensors, thats the weirdest part! It wasn't a matter of tire pressure!! We kept the rear tires 245/40 and changed the front to 235/40. On many other AWD cars that I have worked on I have done the same and never had this issue. But on the last part of your last post is what I am trying to say, the "contradictory input."

Like I said again I did every inspection I could and checked the wheel speed sensors and they all checked out and were working! Only thing that pops up once the vehicle reaches operating temp is the AWC service light but no codes what so ever! Then once we were able to find a new pair of 245/40 for the front, we swapped them and the AWC service light never came back on and the AWC system was working to specs! What must of happened was that the wheel speed sensors abnormal readings from the wheels rotation due to the 235/40 in the fronts and caused this to happen, there were no codes but was just over looking the basics during my inspections without any codes or check engine light.

I've also seen this happen to clients putting on aftermarket wheels on the EVO X's and either had to buy aftermarket ones or have them reprogrammed to fix this issue. But i'm sure this is not a common problem. Never said it was, i'm just stating from what I have seen and fixed with several diff EVO X's.

 

Well if thats a thing from corporate then I am not aware of it cause a have quite a few friends that are techs at mitsubishi and they tell me that they do not check for ECU reflash's when a EVO is brought in for reg maintenance, unless the vehicles problem could have lead to the ECU's reflash but will not erase it without the customers approval. And we do the same at our shop.

Corporate might be telling its dealers to check the ECU but the people working at the dealers such as I are not strict about it. For major system failures thats a diff story, but besides that no one cares if the ECU has been tampered with our not.

 

SSP cooler if you plan on doing anything more intensive than aggressive DD but otherwise just changing the trans fluid regularly should be fine.

 

I apologize profusely for my previous misunderstandings of your posts. It never occurred to me that anyone would do something this silly to an Evo X and then discuss it in public.

 

*fixed

 

^^^^ Hahahahahaha.

And yes, ILOVEBOV, no wonder you have issues. It has nothing to do with your wheels. You can't do that with tires on an Evo..
