Pre Dyno Checklist, What to Check So You Are Not Turned Away!

It is vitally important to do your own pre dyne checklist before even taking your car to the shop to be tuned. For those who are new to getting your car tuned you can be turned away for many mechanical reasons when it comes to the car. It ultimately wastes your time, the tuners and the shops so doing your part will ensure that everything runs jus that much smoother. It is your responsibility as the owner of the car to ensure that these things are as mechanically sound as you can possibly get them. It is understandable that some things will go wrong or that there is an issue that you may not know about but do your best to try and mitigate those issues prior to taking your car to the shop. Happy Tuning and hoping the best for your car!

My tuner was so cool, he found a misfire due to a broken spark plug and stopped the session and replaced it for free and continued with the tune!

+1 for fuel filter! Was dyno-ing my subie. Tuner said I was losing fuel pressure at high rev. Thought it was my pump going... found out my in-tank fuel filter was splitting open at high pressure

[@Jonathan-yk4du]

As far as the compression test goes, I’m going down to Bren tuning for a dyno in a few weeks and that was an item they specifically mentioned on the checklist they sent me.

[@Smeedia]

Some shops require it, others suggest it but its not a bad thing to do regardless

[@Jonathan-yk4du]

Smeedia yea they just sent me that checklist today and I saw your video just after I reviewed it, there were a bunch more similarities haha.

[@rhito68]

Excellent. Saving this list for later... hopefully... pretty sure my wife will go crazy if I do anymore upgrades though so maybe not. Still it was very interesting and something I hadn't considered before.

Smeedia do you know where you could get any genuine WRC parts for subies?like roof scoops, fenders, etc.

[@Smeedia]

I've seen some on a FB group called top end JDM rare parts

[@Kichizo_DJ]

I’m actually 80% g for possibly my first dyno tune possibly end of June! But depends really my states travel restrictions... didn’t think about the diff and trans fluids will look into that for sure

[@Smeedia]

Not a bad thing to swap out, they're going to do a lot of pulls so its a good idea to have freH fluids in there, and hoping that your able to get on the dyno!

[@Kichizo_DJ]

Smeedia yeah lol I gotta fix my drive seat tho. One of the cables to adjust the distance fell off so it’s basically set for my short ass legs haha it’s a good anti theft system tho anyone taller then 5’4” won’t make be able to drive it. Plus the wheel is a qr 3” deep dish haha

[@Chuys_Rd1]

My tuner told me breaks really don’t matter. They won’t touch the breaks at all during the dyno session, that’s what the rollers are for. But everything else is on point. Fuel is a huge one too! Make sure you have good fuel in your car!

[@Smeedia]

Yessss, don't show up with no fuel 😅 and the brakes may depend on the tuner, not sure but regardless brakes should be good anyway 😂

[@88selfsti28]

I was told because of the flex fuel tune that I should bring the car in with a 1/4 tank of 93 and bring or purchase at their shop 5 gallons ethanol.

[@Chuys_Rd1]

88self Sti yup. That’s exactly what I did. 91 oct 1/4 of a tank. And I brought 10 gallons of e85 so I could make a e60 blend.

[@MrHanzda]

A/f sensor,O2 sensor gets the gremlins sometimes and good luck with the stock clutch mine started slipping within few days of stage 3 1050X ots before protune.

[@MrHanzda]

@@Smeedia the Clutch started smelling bad driving at higher rpm's not even beating on the car below 4k no issues and upgraded before protune.

I'd also add to make sure their tires are rated for the speeds their trying to obtain.

Also a very good point to make sure of

[@hgp7605]

Can you make a video showing all the filters we should check? I know about the intake filter, the cabin filter, and the in tank fuel pump filter, but I’m not sure which other ones there are.

[@Smeedia]

Those are really the only ones that need attention, outside of that there are a few small ones that don't generally need to be changed for long service intervals

[@fritziepup]

*laugh* You know, going into the tuner here for my 2nd run/tune after the latest round of installs. I've wanted to have a good checklist of the things to make 100% you're ready, and low and behold, you just created one with pretty much all the things! I also have to say, doing a lot of the things you've added so far, I don't know how you're doing this all without a lift. Oh man, the Down/Up pipe changes, up down up down... Keep up the great work!

Not having a lift definitely makes things more annoying but still have to knock them out 😅 and glad the list will help!

Make sure to update your access port

@smeedia Is your engine guaranteed on the dyno? Like after they do the pre dyno check and say everything is good to go, is your engine covered if it blows up. What if the tuner stuffs up your tune and it blows up!?

If it blows up it blows up lol, the pre dyno check just makes sure the car is capable of going on the dyno. If it gives out I still have to replace it lol
