Stint planning, fuel strategy, tyre degradation — plus a real-time cockpit that makes the call during your race. Built from your own telemetry, shipped and working today. Now I need serious endurance racers to run it in anger and tell me where it falls over.
Join the DiscordAB Racing Line already coaches you corner-by-corner and recommends setup changes from your telemetry. The endurance tools add two things on top: a Strategy tab that dissects a race you've finished, and Strategy Live — a cockpit that reads your race as it happens and tells you what to do about it.
A real fuel profile — a heavy tank burns more than a half-empty one, so your race never gets flattened into a single average. Stint length, stop count, conservative vs aggressive plans, and what lifting-and-coasting would actually buy you.
Are you limited by fuel or by tyres? Degradation measured as real lap-time loss per lap — and honestly separated from your own mistakes. Plus your clean pace vs your actual race pace with traffic and cautions in it, which is what a stint plan should really be built on.
One button. It reads your live race and leads with the call: pit now, pit in 4 laps, you'll make the flag, or save 0.15/lap. Fuel remaining, relative & leaderboard, live track map, tyre temps — and whether you'd rejoin into clean air or straight into traffic.
All of that is built and shipped — this isn't a roadmap. Which is exactly why I need you: it works on my races, on my data. I want to know what it does on yours, in a real race, when it all goes sideways.
Free 60-day promo code redeemable the moment you're approved. Full app — corner coaching, setup recommendations, telemetry, the lot. No payment details required.
After your 60 days end, subscribe at the original founder's rate of £3.99/month — locked forever. Even after the public price rises to £5.99/mo (2,001+ subscribers), your rate stays £3.99 for as long as you remain subscribed.
Endurance racing is complex. The strategy engine needs validation against real data from real races across every category — not just GT3 at Spa. I'm offering meaningful rewards because your IBT files and feedback directly shape what V1 ships with.
Either Road OR Oval license. Consistent, clean data is essential — Class B is the floor.
You race official endurance events, hosted leagues, or regularly drive 1h+ practice stints.
All tester communication happens in the AB Racing Line Discord server. Free, takes 30 seconds to join.
The app runs on Windows. macOS and Linux not supported in V1.
The engine is validated against a lot of my own data. What it hasn't seen enough of is other people's real races — the messy ones, with cautions, traffic, long stints and a stop that went wrong. That's where it'll break, and that's what I want.
I do not want your setup. I'm not asking for it, I don't want it, and I wouldn't use it. Your setup is your work and it stays yours.
What I'm asking for is the iRacing baseline — the stock setup that ships with the car, that every single owner of that car already has, that you'd load and then immediately start changing. It isn't yours and it isn't mine; it's iRacing's, and it's identical in everyone's garage.
I read the parameter names, the adjustment ranges and iRacing's own setup notes out of that file — what the car can do, not what you've done with it. That's what lets the app say "soften the rear anti-roll bar two clicks" for your car instead of shrugging and giving you generic advice. Setups are never published, never shared, never handed to anyone else.
There's no test protocol any more. I used to ask people to drive sterile solo runs; I've got plenty of those now, and they're not where the app breaks. The messy stuff is the valuable stuff. Race it properly, then send me the file.
A race that threw a caution, or a long race with several stints. Those are the two things the app has genuinely never been tested against on real data — every file I own ran green from lights to flag, in one big stint. If your race was chaos, I want it.
Everything in AB Racing Line runs locally on your machine — your telemetry never leaves it unless you choose to send me a file. If you'd rather test the app and send me no files at all, that's completely fine. Feedback on its own is worth plenty.

Raul adds you to the private endurance testers group and you get your 60-day code immediately. Install the app and you're straight in.
Use it on your own races — Strategy after, Strategy Live during. Tell me what's wrong. Drop any race files (or a baseline setup) into the shared folder and ping me.
No. Absolutely not. I don't want your setup, I'm not asking for it, and I wouldn't use it if you sent it. Your setup is your work and it stays yours.
What I ask for is the iRacing baseline — the stock setup that ships with the car, which every owner of that car already has sitting in their garage. It isn't yours and it isn't mine. I read the parameter names, the adjustment ranges and iRacing's own notes out of it, so the app knows what that car can do and can give proper advice for it instead of generic rules. Nothing I do with it reveals anything about how you set your car up.
Close to none. There's no test protocol any more — you race what you'd race anyway, and use the app on it. If you want to send me a race file afterwards, that's a drag-and-drop. No deadlines, no quotas, no homework.
No. Honest feedback from real races is worth just as much to me as data — arguably more. If you'd rather test the app and send nothing, that's completely fine, and your access and founder's rate are unaffected.
Not at all. The engine measures your consistency, your fuel burn and your degradation — not absolute lap times. A steady 1:38 at Spa is more useful to me than a 1:32 followed by three spins. And frankly, if the app only works for aliens, it's broken.
The messy kind. Two things the app has genuinely never been tested against on real data: a race that threw a caution, and a long race with several proper stints. Every file I own ran green from lights to flag in one big stint. Traffic, a scruffy stop, a spin — don't tidy it up, that's the bit I need.
They sit in a private folder only I can see, and they're used purely to test and improve the app. Never shared, never published, never sold. Ask me to delete them at any point and they're gone, no questions.
Worth saying too: the app itself runs entirely on your own PC. Your telemetry never leaves your machine unless you personally choose to send me a file.
The moment you're approved as a founding tester — you're flagged with the founder's rate permanently. After your 60 days free run out you can subscribe at £3.99/mo, and that rate stays with you for as long as you stay subscribed, even once public pricing rises to £5.99/mo.
The 60 days free are yours regardless — I won't chase you. The lifetime founder's rate is meant for people who actually help, whether that's a file or just telling me what's rubbish. Please don't sign up purely to farm a free trial; that isn't what this is for, and it's a small enough programme that I'll notice.
Very much so. The whole point of a small tester group in Discord is that you get direct conversation with the person building it. If there's something the endurance tools should do that I haven't thought of, the tester channel is exactly where to say so — several features in the app started life as exactly that.
One Discord click. Real rewards. Help build the most accurate endurance race strategy manager on iRacing.
