This course is for you if…

🎧
You validate by ear
You already deliver files, they pull well, the customer is happy — but you have no data to say the engine is running healthily.
❓
You have had a comeback
A failure after your work, and you could not say whether it came from your map or from a fault that was already there. Without logs, you could not.
📈
You want to charge more
A validation report with real curves justifies a price that promises never will. It is what separates you from someone who just flashes files.

The full programme

Nine chapters on recording, reading and deciding — from buying the hardware to the words you use when you turn a job down.

01
Why a file that “works” is not enough
The three ways a poorly validated Stage 1 fails, what the customer never sees, and the case of a file delivered without logs — failure three weeks later.
StakesLiability
02
Logging hardware
What is genuinely enough to start with and what is merely comfort. The real sample rate of an OBD tool, the sampling trap, and a tool / rate / price table.
OBDCANBudget
03
Choosing the right channels
The eight essential channels on a turbo petrol, the eight on a diesel, and why logging forty of them wrecks your sample rate for nothing.
PetrolDiesel
04
Recording a usable log
The full protocol: third or fourth gear, full load from 1,500 rpm to the limiter, one variable at a time between runs. And what invalidates a recording.
ProtocolMethod
05
Reading a boost curve
Requested pressure against actual pressure, the overshoot off boost, the drop at high rpm. Three annotated curves: one healthy, one with a leak, one overboosting.
TurboDiagnosis
06
Knock, and why you never hear it
Reading ignition correction per cylinder and never the average, the thresholds that decide, and the false positives that cost you timing for nothing.
KnockTiming
07
Fuelling and engine safety
Target lambda against actual lambda, the areas where a lean mixture is fatal, the corrections the ECU applies silently, and the threshold never to cross.
LambdaInjection
08
Deciding: deliver, correct, or refuse
The 12-point validation checklist, what a map can fix and what is mechanical, and how to turn a job down without losing the customer.
ChecklistCustomer
09
Three real validations
A VAG 2.0 TSI validated in three runs, a BMW N57 whose boost falls away, a Renault 1.6 dCi with knock corrected. Raw log, reading, decision, outcome.
