If you are up to it, id go with a nice external pump made to work with the stock tank simple because it will be the easiest to troubleshoot after you finish the initial install.

The downside is...

thats disappointing :(

Are you using a Megasquirt output to drive the fan? I cant remember

Ed, what rad. are you running currently?

My coolant stays at about 180-200*F depending. I dont know what causes it but its always gone higher while under boost. I think my CLT sensor is just wacko or I have air bubbles or my rad just...

Ed, I am going through your tune and my tune right now. I stole some things here and there but one thing that I am curious about is the MAT correction table you mentioned a little bit ago. This is...

of you mean dont do what i did lmfao :)


Yes I had no idle control and was usually fine. In the cold I helped it idle and if I had a rough tune I would have to help it idle in the summer until...

That would be awesome.

I too found the richer idle to be easier to control. Im not sure what the pulse width was on my injectors at the time but im sure it was very low if i tried to run lean!

Ed, mind letting me peak around in your tune? I spent some time changing things on mine the other day. Something I need to look into is barometric correction and the MAT fuel correction like you...

Are we in agreement that this issue would be worse under boost?


I was thinking something along these lines. When I ran into problems with carankcase pressure, First I just vented the valve...

I think a catchcan or some other proven method of keeping the crankcase from pressurizing is a must for any turbo car. our PCV valves were never intended to see boost.

Im curious what the results would be with a catch can hooked up the way I do it

Valve cover ran to catch can, catch can ran to pre turbo. This has always worked well for me. I would be able to...

You are running a stock pcv valve routed into the stock locations? DONT DO THAT. Thats something we rarely talk about and I dont know why because it caused me huge issues. With boost I was...

any chance your spirit's turbo will drop in to triple check?

Compression seems "normal" ?

How exactly is the PCV system hooked up? Do you have a catch can and how is that tied into everything?

and im just sitting here with a good ol 3.0

Brent loved the change to 10:1 pistons, thats something to consider. Felt like the motor was much more responsive going from vacuum to boost.

I would try .030-.035 before overthinking things

^ ^ good to know because I kinda dented my pan the other day :( Ed, what spark gap are you running? I cant remember when I had blowout but .028 (or .28?) seemed to fix that. Blow out feels like...

at 15/16psi, I was maxing my injectors out. Now with my 270* cams, Im maxing the injectors at half the boost, or close to it. A large turbo, e85 and headwork will get you close to 500 under 22psi...

stock MS map is a 2.5bar mounted inside the case. good for 21.5psi I think. Not doing the math, because im feeling lucky ;)

Yeah, ShadowDash can upload and store your logs in MGV format. ShadowLogger could not store them in the same format and had to be uploaded to get converted, and then re downloaded. It was a pain in...

I bought Shadow Dash. When talking with Phil on the phone he mentioned that he plans to make it a full scale tuning app just like Tuner Studio.

Right now you can log native Megalog viewer data...

My cheepy cx racing intercooler has always kept temps really close to ambient but I haven't gone over 16psi really. IT should work just fine for a efficient turbo that doesn't heat things up much...

i just idled the car in the 14-13 area.

Megasquirt was so much fun, i got good at figuring out what misfire came from what and why. kind of miss messing with it. Its so cold right now that i...

we fried the ecu in my buddies GSX.. his dad opened it up and re soldered the connection that broke. it was very obvious. could be the same deal with brents and ed's ecu. Ours are a pain in the...
