Well I went and got my car dynoed these runs were made at 7.2 psi and are sae corrected, I have my mevi activate at 5k rpm but theres a nasty dip in power right at 5.75k for some reason, and now that I see I need to make corrections to my a/f but i dont think it hurt the graph any. POsting 2 top runs, I will also host the run files somewhere and post em on here for those who want them. I think at another 2.5 lbs I can make what mike is making.
Also on the way home I was kinda pissed that I didnt hit over 9lbs off the .7bar spring so I was messing with my ebc and I go to boost and hit 12.4lbs alsmost **** myself but the car felt amazing and noithing happend, no knock, no wierd engine noises, nothing blew up,.......kinda tempted to see if I can boost 11lbs. Dont know....

EDIT:I didnt get to run the JWT ecu along side this stock one because I really didnt have time to do the swap as it was a dyno meet and tehre were a lotta people to get out before 6pm. Im going back this upcoming saturday again to see if I can push out the 9.5 psi I want and also to touch up my a/f on the dyno machine. Near the end of my hour I will be swapping ecus's to compare numbers.

 

nice numbers, as soon as you put in the JWT ECU expect to see about 270whp.

 

HEre are the run files for the graphs. I need to figure out why i get that dip after 5.25 to like 5.85rpm cause thats a drastic dip for no reason if my mevi opens up at 5k rpm.

What gear did you dyno in? Also remember you will see more boost on the street than you see on a dynojet because there is hardly any load on a dynojet.

 

It is 4th gear, i figured out the ebc settings to get the 9.5 lbs I want on the dyno, this sat I have a whole hour to do whatever I want on the dyno machine, i wanna figure out the spike, fix my a/f and do the jwt/stock ecu comparisons.

 

Do you think that spike at the end of your dyno is a result of a boost spike or something else? It looks to me like your MEVI might be opening way later than it should though I can't think of a reason why unless you have the RPM switch set wrong. What RPM switch is it and are you using a relay?

 

Summit rpm switch set to 5k, im not sure what you mean by how im using a relay.

 

Well that could be it right there. You have to set the Summit switch lower than the rpms you want it to activate at. It's been a while since I got rid of mine so memory's a bit fuzzy but I think for it to open at 5000 you want to set it around 3200-3300 or somewhere in there.

Did you visually observe where it's opening?

EDIT: as per Sdot's post below, I thought you meant you set the switch to 5000. If that's not the case and it's set correctly then ignore what I said.

 

Is it actually set to 5k on the summit switch or is that where it actually activates?
edit: You beat me Dandy (+1 what Dandy said).

 

The summit activation points seem to be all over the place. I had mine set to like 3200 or 3400 to open at 5200, mike had his set at like 4000 or some crap, etc. 5000 is definately not correct if that is the actual setting on the summit switch. I'm almost positive that's what's going on.

 

Ok that makes sense now, yeah i though if its set to 5k it will open at 5k, but looking at the graphs it looks like i gotta set the ***** at like 4k for it to open at 5k, also i found the problem i had with not boosting the wastegate spring, my greddy type rs bow wont **** down all the way after the releases air, i tried both settings hard and soft and it stays open about 1/4 inch after releasing air, anyone know how to fix this or do i have to go with another company now?

 

Very solid numbers.

You need to start your pull and start sampling at 2K rpm's or so, not 3.5K

Your AF is like I said it would be, peaks and valleys. My AF w/o any corrections looks just like that since the A32 MAF and Z32 MAF have slightly differnent voltage curves. Some fine tuning with the SAFC will fix that.

I would bet your activation on your MEVI is off. There seems to be no exact rpm setting on the rpm switch that give everyone the same results.. Try 3.3or 3.4k and see what that actually gives you. It will take some messing with to get it right.

 

Don't use SAE correction on FI cars ESPECIALLY intercooled turbo ones...

355whp/337wtq are your numbers....

 

here is an overlay of my last dyno. You really have to start the pull at 2k rpm's. Your turbo won't spool the same punching it at 3.5k

 

i see, well i messed around with the rpm switch set it to 3200 and now it activates at 5k exactly and wow what a difference lol, holy cow!!!!. Anyone have any sugestions on the boost thing with the blow of valve, as i further examined it, when i boost it and opnes up to release air and slowly moves back down but doest vlose all the way and leaves about 1/8 to 1/4 whole from which the air is being released from. From my undestanding, when it opens and closes to release air its supposed to do it quickly. Also I realized that when I start boosting again with the bov not all the way shut once it the air flows through the ic piping the vavle shuts all the way down as i press the accelerator. And then it does the whole thing again where it doesnt close all the way and goes down slowly, ill try and take video of it tomorrow morning to show you what i mean, now does this affect anything at all?

 

Also mike I know you have a MEVI installed and looking at your graphs you dont get that huge dip when it actually activates. How did you do that?

 

IMO after looking closer at the graphs your MEVI isn't actually activating until around 5900rpms or at least thats what the graphs show.

 

Yeah I realized that last night and fixed that problem by setting the rpm switch to 3200 and now it opens at 5k, and how sweet it is.

 

How much of a dip it makes, depends on your setup and what rpm u set it at. If you go back to the dyno now that you have it actually opening at 5000 rpms it should be almost gone. That's what happened to me but once I played with it on the dyno the dip decreased.

 

There shouldn't BE any dip where it activates, that's the whole point of setting the RPM switch correctly. The only time there is a dip or jump of any sort is if you have it activating at an incorrect RPM.

 

What they said

 

Hey, those are great numbers man. Did you get those PR mounts in yet? How do they feel?

I didn't realize you guys had problems with the Summit switches activating at the right time. I have mine set at 5000 and it opens at 5000. Is it just you FI guys that have the problem? Ever tried a VAFC? Does the same thing happen with the Harlan?

 

If you have it set to activate at 5k it should open at 5k no matter if you're boosted or not.

 

The reason the summit switch doesn't activate at the RPM it is set at is because it is not set up for 6 cylinder cars. All it does is count ignition pulses, but because 4, 6, and 8 cylinder cars have different #s of ignition pulses per any given unit of time, you have to compensate.

 

So then why does it work normally for me, but not for others?

 

No idea. Maybe whoever makes them for summit has different versions for different cylinder counts, or maybe there is a setting somewhere on there that isn't listed in the documentation, that changes it from 4 to 6 to 8 cylinder operation. You are the only person I've heard of who has the thing switching at the exact RPM setting.

 

Getting the pr's in this sat.

 

Congrats,that's some great # for 7.2psi.Keep us update when you redyno,thanx.
