How many miles before getting a tune?

[niterydr]

I prefer when possible to seat rings on the dyno and immediately move to tuning.

Street cars= Idle/startup/check over, change oil.
Vac pulls (20 or so miles) Change oil

Begin tuning non high load stuff for a few hundred miles, change oil at 500 miles. Depending upon rough in mileage period, start tuning high load around 100-200miles.

Having it broken in on the dyno was another thing I have been thinking about because I have changed a few things from last year and it was never fully tuned last year and I definitely don't feel comfortable messing around with afrs or timing with aem. It just seems most people don't recommend breaking it in on the dyno.

Weather its on the dyno or on the street I just want to make sure it's done right

The car is tuned for wide open throttle so no reason to worry about any issues with the tune.

[4seasons69]

The car is not tuned for wide open throttle right now. That's part of the problem

Hey 4seasons, I'm in the same boat with my Evo 8. I got the engine rebuilt and installed by MAP. The "Oil Changes and Intervals" sheet we got is misleading. It is prepared for conventional oil break-in, with change intervals at 50, 500, and 1500. The problem is MAP uses Amsoil Break-In oil for their new engines and what was discussed with me was there's an initial break-in and tune for about 25 miles, an oil change with new Amsoil Break-In oil, and then run it to around 1500 miles, at which point it is recommended by Amsoil to switch to Dominator synthetic oil.

I've read somewhere that Amsoil recommends using Break-In oil for a maximum of 1000 miles. With that, I'm going to run my current Break-In oil (in at 25 miles) up to the 1000 mile mark and then switch to Dominator. I'll get it retuned at that point too.

Then.... I'm going to fuck shit up

Correct.

[4seasons69]

Right now my plan is to run the amsoil break in for 20-30 miles, change the oil and filter run amsoil break in again up to 100 miles, change the oil and switch to conventional, then switch to synthetic at 1500 miles. I'll probably bring it to Shane for a tune around the 500 mile mark

I should back up and ask where you're at in the process. Did MAP A)rebuild your engine and you installed it, B)they rebuilt and installed it, or C)they rebuilt, installed, and street tuned it?

Map built my shortblock, cylinder head express built my head, I assembled the long block, and pushit2.0 degreed my cams. Then I installed the engine. It is running on a partial tune from last year that makes it driveable but I can't beat on it. So once the initial break I am of the engine is done I will be bringing it to Shane up at db performance for a tune

Gotcha, so you would work from the initial break-in period. Sounds like you have a good plan. I believe most guys use a different weight oil during break-in too, like a lighter 5w-30 before going to 20w-50.

[4seasons69]

Yeah one I switch from the amsoil break in I'll probably run a 5w30 conventional at least until it gets warmer out

MAP has a dyno, I doubt they street tune anything. They may check or verify a dyno-tune on the street, but that's probably it. No legit shop would risk street tuning a car; fast way to get shut down and assets seized/awarded.

Dyno isn't up and running yet. They had some issues with the builders but moving forward on it recently I believe.

Shit, they're in the middle of nowhere now. You could hide all sorts of bodies over there. Street racing anyone? LOL

[goodhart]

idk, they were looking for a tuner last I checked. Not sure getting it tuned there is even an option right now.

Wat?

Wat?

Last I heard they still have Jordan, unless he just quit or maybe they're looking for another.

Regarding your "Wat?", just imagine the lawsuit if they were to crash a car while street-tuning. From the car's owner, driver of the car they hit, any passengers they hit, owners of other damaged property, etc. Basically, a good lawyer would put them out of business since I guarantee no business insurance policy covers illegal street tuning, and no tuning waiver will hold up in court if it was performed illegally.

Jordan's still there. He helped me when I picked up my car. He's not going anywhere. He hangs out there on weekends for other stuff too

Yea, old school DSMer/Fabricator Wes Hess died in a street tuning accident a few years back.

Correct, except street tuning should be performed under safe conditions and legal conditions. Unless the chassis dyno has the ability to dial in load and hold for load sells, everything else is just an educated guess; thus the need for street tuning for dynojet tuned assets; you can't hit the part throttle and low load stuff on those.

Eh crap, 4 Seasons went offline. If MAP built your car and then tuned it, they *should have* changed the oil after the initial break-in and tuning. I would run the included Amsoil Break-In oil 500 miles if you're going to change it and get a tune then.

It's not tuned, this thread is about how many miles to put on the car before tuning. Looks like he is bringing it to DB after initial break-in.
