Yeah, there weren’t any major changes in the logs — just some slight ignition timing corrections after installing the gearbox from the Speed3 Gen2. I can share the logs a bit later.

Re: My Speed 3 isn't making power.

Small list of what’s been done so far in the search for the issue Things already tried: Replaced MAF Replaced ECU Replaced O2 sensor Replaced bypass valve Checked timing marks, trigger wheels, and valve clearances Ran the car with the exhaust removed, only on downpipe Swapped in a turbo from a prove...

Re: My Speed 3 isn't making power.

What you can do is to disconnect the hose between the compressor housing and the wastegate actuator (disconnect it from the wastegate actuator and cap it with a screw) and make a test at like 50% throttle. This way you will know if the problem is on the exhaust or if it's on the wastegate actuator/...

Re: My Speed 3 isn't making power.

BPV CorkSport. MAC solenoid, line diameter is around 4mm. Сonnected like this: Check the MAC valve and see if that cap it has did not fall off. If it did then replace it and on the new one use some duct tape all round to force that cap to stay in place. This is one of their weak points but it's an ...

Re: My Speed 3 isn't making power.

As expected, the throttle body didn't help with the issue — but I was still hoping it might :cry:

Re: My Speed 3 isn't making power.

What is your EBCS setup? How is it connected, where, what line size are you using and what EBCS is it? Also, what BPV/BOV are you using? I do not think your throttle body or intake manifold are the problem. A stock turbo flowing 250+ g/s of air at 70% WG duty is normal. Also you seem to be at a pre...

My Speed 3 isn't making power.

So, I have a 2008 Mazda 3 MPS with a built engine — Gen2 pistons and Eagle rods. It's FBO with downpipe, HPFP, intake, FMIC, and so on. Stock turbo, intake manifold, and exhaust manifold also stock. It's a pretty typical setup that should be doing 100–200 km/h in around 12–13 seconds and making abou...

Re: Shift related tables

It's a multiplier for the target load in the next gear in that RPM/throttle position point. So it doesn't help and it doesn't stay in the way either, it just is, and you can set it to your preference (you can fill those tables with '1's and that's it - if that's what you want). Sometimes right afte...

Re: Shift related tables

I played with those tables a bit. There is no performance increase there, it will only affect the load value and load ramping after shifting to an upper gear. If you WOT shift, the stress on the clutch and the rest of the drivetrain will be higher if the values from the shift point are closer or eq...

Shift related tables

Hi there. Has anyone tried experimenting with tables from the Shift Related group. Is it possible to get some increase in performance when shifting gears? Please share your experience :burnrubber
