Nice numbers there Thien.

someone correct me if i'm wrong, but what is the point of a tune in very cold weather when the average temperature the car will be at is much higher? I understand doing a dyno in colder weather (better numbers), but why a tune?...do you have different maps you can switch between?

Whenever you modify your engine with more than just bolt ons, you need to tune it.  If you don't tune your motor, you're going to run rich or lean (depending on the modification) and will damage your motor.  In Thien's case, he was running incredibly lean because the SC was forcing more air in the combustion chamber, but the stock ECU was not providing enough fuel to compensate for the forced induction.

i understand that, but shouldn't you tune at temperature that the car is going to be running at a majority of the time?
It just doesn't make sense to go get a tune at 40 degrees, when summer is just around the corner and the car is going to be driven in much warmer weather.

I guess you don't get the point of tuning then Sam.  If he didn't tune his car, he would DAMAGE THE MOTOR!  Isn't that reason enough to tune it as soon as possible?  Sure, different temperatures can affect the performance, and fine tuning it for those changes is good practice.  But think white and get serious.  Engine reliability trumps performance.

But think white and get serious.

what the hell is that suppose to mean?

He has had the SC for atleast a month now, has this seriously been the warmest day? If keeping the engine from blowing up was a major concern, I would figure he would do that within the first couple days (if not immediately after)...


and just for the record, i understand that a tune is important, im advocating that he should have tuned a long time ago...not a month later on a cold day

OK, It was tuned 2-3 week ago. The shop that did the tune half assed it. So, I took it to another shop. I scheduled the dyno and tune for today, but I scheduled it 2 weeks ago. I did not think it was going to be 40 degrees out. Sorry, I don't live in Texas where its hot and has a steady weather condition. Here in Colorado, it snows in April and/or in May, and you will never know if it'll snow or not.

that's what i wanted to know...i knew your were smarter than letting your car run for over a month without a tune

Beyond impressive.......way beyond. I'm curious how tough the torque steer will be to control. Will you be using a 5W30 synthetic oil?

[MyNameIsThien]

I am making the switch next oil change from Mobile 1 5W20 to Mobile 1 5W30. As for the torque steer, it does get a little crazy if I put the pedal to the medal.

nice looking accord !

[neoryan7]

Looks great! I noticed you did a cluster swap too? how hard was that?

[MyNameIsThien]

I didn't do a cluster swap.
