Because mine are too small

Welcome!

One of my great regrets is passing on the opportunity to by a Mk1 MX5 with a supercharged V8

Due to Google policies, MSDroid is effectively dead so I'm scratching an itch with a web browser based app for tuning Megasquirt and Speeduino type ECUs. I need data to test the auto VE tuning aspect. If you have a reasonably well tuned setup, can you please send me you MSQ and MSL files? I want to ...

Also, if you have it in a Miata, post some photos

And the same to you. Hoping for a bit of garage time later

Excellent news!

Looking better than ever!

Can you attach the complete log? If not, email it to me at dave.g.smith@gmail.com

That's very expensive, have a look at OBP https://www.obpltd.com/product-category/fuel-water-swirl-pots/bulkhead-mount-swirl-pots/ A return form the fuel rail keeps the fuel in the rail cooler.

It isn't really a return on the expansion, it's a vent for excess. Either dump it or catch it in a bottle and if you have the right pressure cap it'll get sucked back in as the water cools.

What does your waterpump look like? Every connector on it is an input so one of them can be used for the output from the inlet manifold and the heater matrix. The expansion tank is either just a vent or goes to a catch tank dependent on if you have a two way cap on it or not.

Hi, from Argentina. I've rebuilt several Mercedes from the 80s and 90s. I've had no problems with 4- and 6-cylinder models. However, I'm currently building a W126 V8, and I can't program the fuel injection. It always comes out too rich. I use Tuner Studio and simultaneous fuel injection. Any ideas? ...
