Creating A Base Map | Where Do I Start? [ HPA Q&A]

Creating a base map often seems like a daunting task, but it doesn't have to be.

Why you would create your own base map instead of relying on something else's, and where you should start are covered in this Q&A with Andre.

That sounds easy. I'm doing a Franken CIS install using Microsquirt adapted to run the Bosch KE-Jetronic on the Merc 80s SOHC i6, which almost nobody does since they all swap in a later 90s DOHC i6 version of the same basic block but I prefer the note to sound correct for the period of the car (tuner version of my model should sound lumpy idle, not rice cooker imho). So there's no base tune around to download. It's 30/70 which is a long way from 16/58 stock timing and that was throwing me a bit, since I'm learning as I go and blew out most of the budget on the mechanical build. Guy who did the engine is doing a very neat Franken install with the right sensors as I write this so I'm already thinking about the tune, which will be a blank slate. Bloke who makes the system is in another state, so that was going to get expensive getting him in. But as you say if I just set the VE table to 60-70 and the ignition to 15 degrees across the board I can get it running safely at least and then start refining the tune from there? That's a lot easier than I thought it was going to be, everything on the web is all about tuning Microsquirt/Megasquirt for turbo LS motors and that sort of thing, with big numbers all over the place. Yours is actually the first vid I've seen starting at the base like this and I had no idea what to start with or how to. THANK YOU.

This is where I'm at now. I'm trying to tune my mustang with a 427 V8 and my problem is there are a bunch of lean holes and rich holes in the ve map. This makes it very hard to road tune by myself since there is random, violent bucking, surging or backfiring. Any one of these events happen so fast that i cannot add or remove fuel in those areas. I have an autotune option that references the AFR table, but how do i know what to put in these trouble areas of the AFR table? Do i just make both the VE and AFR table very rich and cut the fuel down while driving? I'm using a MegaSquirt PnP Gen 2.
Thanks HPA

Have you ever did a live tuning session where u explain as u do?

Unless you seriously overfueling due to dodgy ecu
