left is AFR and right is VE
Hey everyone, this might be a newbie question, so thanks for being patient with me—I’m still learning all this stuff!

I want to load a base tune from Turbo Kitty for my 1993 1.6 turbo. When I opened it on my desktop to check it out before I burn it, I noticed something odd: the AFR table (on the left side) goes up to 14.5 psi of boost (200 KPA), but the Fuel VE table only goes up to 101 KPA, which is just barely above atmospheric pressure. Why is the tune set up like this? Shouldn’t I adjust the Y-axis on the VE table? If so how, do I just copy the AFR Y-axis?

Also, I only want to run 5 psi of boost for now, just to be safe. Do I need to adjust the Y-axis on both the AFR and VE tables? If so, is it as simple as setting the highest Y-axis to 135 KPA and scaling the rest down to 20 accordingly?

I know there are other settings I’ll need to tweak to run 5 psi, like boost cut and some others, but for the AFR and VE tables specifically, is that all I need to do?

After I am confident in the base map or after adjusting the VE map in the base map, My next steps are:

1. Burning the tune into the ECU
   
2. Calibrating the gauges (AFR) and the sensors
   
3. Changing the injector size to 420cc as I am running rx-8 injector
   
4. Remove fuel pump fuse and correct mechanical timing to ECU timing (10 degrees advanced)
   
5. Idle the car (hopefully starts up)
   
6. Drive it slowly around the block letting VE live analyze do its thing while checking my AFR's
   
7. Continue to dial in the base map in for my car using follow OGPedXing’s tuning guide on youtube and turbine research.
   

Just wanted to run this by y’all to see if I’m missing anything or if there’s a better way to approach it. Please feel free to give advice or better resources. Thanks for the help!

 

Just keep poking around and watching videos and you'll get it soon enough. Sounds like you have a lot to learn still. There are plenty of video's/courses out there that will help. Actually playing around with the ECU in the car will help a lot as well.

You can't copy the axis values IIRC, you have to enter them manually. The VE table is setup for a naturally aspirated car, probably for extra resolution if you're not running boost. The VE table doesn't need as much resolution, so the boosted map was probably left in because you wouldn't change much with the extra cells. The axis values on the map have no effect on how much boost you're running. If you set your ve table to max at 100 KPA then the 100 KPA value will be used for anything over 100 (if it's not obvious this is bad and dangerous).

If you don't have boost control (electronic or manual) you don't get to choose how much boost you run. It's going to run wastegate pressure which is likely going to be higher than 5 PSI.

 

I would heavily recommend utilizing over-boost protection, but also instead of just setting your top setting to 5 psi setting it to 12 or so to give yourself some headroom in the event of an over-boost condition.
