We Send You a Basemap
Within 72 hours of payment we'll send you a starting basemap. Flash it to your car using your tuning app and get it running.
03
You Send Us Datalogs
We'll tell you exactly what datalogs we need based on your platform and setup. You capture them during normal driving and send them back to us.
04
We Tune & Send It Back
We analyze your logs, make changes to the map, and send you an updated tune. We repeat this process until your car is properly dialed in.
05
You're Done
Once your tune is finalized you'll have a safe, reliable, and optimized map. If you ever want to take it further, come see us in person for a full dyno tune.

Eligibility Requirement
Your car must have a good factory wideband and be capable of running full-time closed loop. If you're not sure whether your setup qualifies, fill out the form below and we'll let you know before you pay anything.
What You'll Need
Before You Order
Tuning app or software — Cobb Accessport (WRX), Ecutek (FRS/BRZ), Hondata Flashpro (Honda/Acura), or MHD (BMW)
A stock or healthy engine — we won't tune a car that has underlying mechanical issues
Factory wideband O2 sensor — must be working correctly and reading accurately
A safe place to drive — you'll need to capture datalogs during normal driving conditions
Email access — all communication and file transfers happen over email
Time Limit
4-Week Window
You have 4 weeks from the date of purchase to complete your e-tune. The timer starts the moment you pay — not when we send the basemap.
If the 4-week window expires before your tune is complete, the process ends. No extensions, no exceptions.
If you haven't heard back from us within 3 business days, check your spam folder first — then follow up by email.
Do Not Order If...
Read This Before You Buy
We want this to go smoothly for everyone. Don't purchase an e-tune if any of the following apply to you right now:
You are still waiting on parts or they haven't shipped yet
You are going on vacation, deployment, or will be unavailable in the next 4 weeks
You do not have a safe place to do wide open throttle pulls
You do not have reliable email access and a computer to transfer maps and logs
Your car has known mechanical issues — leaks, misfires, worn plugs, weak fuel pump, etc.
Your wideband O2 sensor is not functioning correctly
Liability & Warranty
Important — Please Read
By purchasing an e-tune from Church Automotive Testing, you acknowledge and agree to the following:
No engine or vehicle warranty is expressed or implied. Tuning involves inherent risk. There are too many variables outside our control — fuel quality, maintenance history, pre-existing wear, part tolerances — to warranty outcomes on a remote basis.
You are responsible for your vehicle. Church Automotive Testing is not liable for any engine damage, mechanical failure, or property damage that occurs during or after the e-tune process.
Wide open throttle logging is your responsibility. Only do WOT pulls in a safe, legal environment. Church Automotive Testing is not responsible for any incidents that occur during data collection.
Payment constitutes agreement. Completing your purchase confirms that you have read, understood, and accepted these terms in full.
