For shop owners

The most expensive job in the shop is the one you already did.

Nobody line-items a comeback. It shows up as a bay that didn't turn, a part you ate, and a customer who quietly books somewhere else next time.

Bay time

Same scale. Only the amber segment was ever paid for.

What it actually costs

A comeback is five losses wearing one coat.

You know this arithmetic better than we do. It’s worth writing down anyway, because it’s the entire case for the tool.

The labor: Paid twice for the same job. The second time at no charge, by a tech who could have been on a paying RO.
The part: The wrong one is already in the car, already out of the box, and frequently not going back to the supplier.
The bay: A lift tied up by a car that was supposed to be gone. Everything behind it moves right.
The tech: The good ones take it personally. Enough of them and your best diagnostician starts padding every estimate to protect himself.
The customer: The only part you can’t price. They don’t tell you they lost confidence. They just stop booking.

On the floor

Three techs, one car, one answer.

Diagnostic consistency is nearly impossible to enforce by policy. Nothing about the workflow changes: same tool, same cart, same way.

Working it from the codeWorking it from the verdict

Your A tech22 years

Coil first. He has seen this exact miss on this engine.

Ignition coil, cyl 1. 87%. Swap and retest.

Your B tech6 years

Plugs first. They are cheaper and he has been burned before.

Ignition coil, cyl 1. 87%. Swap and retest.

Your new hire14 months

Reads the code, opens a forum thread, starts on fuel.

Ignition coil, cyl 1. 87%. Swap and retest.

Illustrative. The right-hand column is the same line three times, which is the entire point.

Your existing stack

It doesn’t replace what you already pay for.

If you run ALLDATA or Identifix, keep running them. They answer a different question than AceDx does.

	Repair-information libraries	AceDx
What it is	A library of procedures, diagrams, wiring, confirmed fixes, and TSBs.	A diagnostician that reads this specific vehicle and commits to what’s wrong with it.
What you ask it	“How do I test this, and what have others found?”	“What is wrong with the car on lift three, right now?”
What it gives back	The reference material to work from.	One ranked call, its confidence, and the evidence under it.
Together	Still the thing your techs open to do the job properly.	The thing that tells them which job to do.

The same goes for your scan tool. AceDx is additive on purpose. Nothing you’ve already bought or trained on gets thrown out to make room for it.

Fair questions

What owners ask us first.

What does it cost?

We haven’t set pricing, and we’re not going to invent a number to fill a page. The pilot is free for the shops that run it, because we need the diagnostic cases more than we need the revenue right now.

Will my techs actually use it?

Only if it’s right often enough to be worth the glance, which is the honest risk and exactly what the pilot measures. A tool that’s wrong twice in week one gets left on the counter, and no amount of shop policy fixes that.

That’s why it commits to one call and shows the evidence. A tech can catch it being wrong, which is the only way they ever come to trust it being right.

How long does it take to get running?

There’s no install. It runs on a tablet and reads the data your scan tool already pulls, so the setup is an account and a login rather than a bay retrofit.

What do you need from us during the pilot?

Real vehicles, real repair orders, and techs willing to tell us when the tool is wrong. That last one is the part that matters. A pilot where nobody complains teaches us nothing.

Run it on the cars you're already fixing.
