i hope you actually have fuel in your tank

 

lol! that'd be hilarious!

I put about 10gallons after I got everything buttoned up!

I think I cut the sensor wire bc I am getting fuel level error in the link.

 

figured i would through that out there since that might cause issues if you didn't

 

Spent the last few days getting the Link sensors pigged/wired in, organized, and pinned to the ECU. I ran the car for about 15minutes with a few throttle blips and logged the parameters to ensure everything is talking back and forth between the ECU and the car.









Pretty happy as I had no check engine lights / faults and the sensors are talking to the ECU. A little more work to assign a calibrations table (based on the sensors pressure range) but overall pretty encouraging.

Possibly (but not likely) a freak-out moment but I am dripping a water-like fluid from the exhaust v-band on the turbo ... I dont think it's coolant as it doesnt have a neon yellow/green tint to it and it's pretty much clear. I can only assume right now that it's condensation buildup/unburnt fuel, etc - essentially the stuff a catalytic converter would burn off. I'm gonna do a better job collecting it next start up ... I can't imagine the coolant jacket is cracked/leaking in the turbo and it really just seems like the first few minutes of running. I have around 14psi of pressure in the cooling system and I can only imagine I'd be pissing coolant 24/7 if this werent the case.

I also got a 1 quart bottle tapped/sealed w/jb weld for water methanol. Put the Snow Performance / NX water methanol kit on the Z and put/putting the AEM (with the 5 gallon tank) on the pickup. The two kits run the same diameter hose so I gonna run AEM style nozzles on both vehicles.








Hoping to get the car on the road this upcoming weekend - spent last saturday out at our local track (high plains) with my buddy/former boss...he and his wife were driving & instructing and we all hung out. During the charity laps, my buddy threw me his keys and let me take his car out (a '16 boxster w/porsche's PDK, he was in the passenger seat). I got 5 laps in, nothing sexy, cant get past 75mph, no passing, all the cars in a line but it was a pretty cool experience none the less. The porsche club puts out cones for the apexes so it was essentially connecting the dots at 50mph. It makes me want to get a track car that much more.

 

Glad to hear everything is coming together.

 

Figured I'd post a few screen shots of the failsafes on the Link. I think these were the deciding factor (and price, compared to Haltech's comparable standalone) Feel free to chime in with any comments on how these tables are setup)


I got the three oil pressure, fuel pressure, and coolant pressure setup and communicating with the Link. The tables below each sensor display is key ... you can program the link to flip the CEL if the sensor reads outside of your pre-determined range.




Further - I setup these 'rescue' tables which I have setup to cut RPMs if the sensor reading is below or above a pre-determined value. I have them set to RPMs but they can be set to other parameters. I also have a max MAP table setup against coolant temp but I'm not as concerned with ECT as I am fuel/oil/coolant pressures.

had a good day and made some more progress with the car ...

got the car up and going and a solid 15minutes of idle / throttle blips and she did well.

With the turbo & header assembly so close to the radiator my 16" spal was too close for comfort to the turbo exhaust housing so I dropped down to a 10" and I wasnt sure if it'd provide enough capacity (around 900cfm...I believe the 16" was 2100 cfm).

As a test, I got the car up to 170 degrees and configured the Link to activate the fan at 170* and let the car run...over a few minutes the car did get any hotter but it didnt get any cooler either. I did the same test for 200 degrees and same result. I do have two 6" spal fans I could hook up to the OEM 'fan #2' power source. We'll see...

my coolant expansion tank (a simple lab-grade nalgene bottle) did fill up maybe 6 to 8 ounces ... I'm assuming this is actual expansion ... I marked the bottle with that rubber band and we'll see if it goes back into the radiator upon cooldown.

Got the car plenty warm and out for about a 15minute test drive. Nothing crazy, stayed in vacuum the entire time with the exception of one pull where I did get into about 2psi of boost - never thought I get excited about 2psi of boost...lol!

I did run into an issue with the Link's failsafes ... it's definately going to take some ironing-out as the car is going into 'safe-mode' during normal operations ...

For instance - oil pressure (I really gotta dial the threshold down) On my way back, I turned around and pressure dropped below 15psi (on the link pressure sensor) and limitted my RPMs to 2500...

Also coolant pressure - my coolant pressure was between 1psi and 10psi the entire trip ... so I was 'checked' to 2500 and 4000rpm most the drive.

The GP (general purpose) tables have timed lock-outs but the others dont - so I might have to rearrange the assignments.

here are some pics from the afternoon:

 

Looking amazing man!

 

Thanks Conway!

I reviewed my data log from the run and used Link's 'mixture map' ... which is a matrix that is setup identical to the base fuel table. The data is then funneled into a this matrix and organized/summarized in a manner where the applicable samples are averaged and each RPM/Load cell has a single correction. You can click on each cell and the software will automatically make the correction in the base fuel cell.

Denver got hit by a snow-storm last two days so I wont have the car out for a few days. Between now and then I'm gonna iron out more of the failsafes to get things working correctly.

 

When you purchased the link i remember you said that it included a remote tune. How did it go?

 

I got a 'base tune' included with the link. Essentially Jason ping'd into my computer, got a starter map installed, my build specifics taken care of and basic fuel and ignition maps setup so I could drive the car to the dyno for a remote tune. I did have to pay for the real tune and dyno time.

I think he put around 60 to 90 minutes of time into getting the base map installed and car up and running. The ECU from PSI was the same cost from anywhere else so I was essentially getting it setup for free and I had an in for a remote tuner. Also PSI was recommended by a fellow member.

 

Your car looks so insane with that frontend. I can't wait to see what kind of times you'll see on the track.

 

Looking good James!

 

thank you to both!

quick update - nothing with the car over the weekend. Ski'd on Saturday and hockey yesterday. Really just been digging into launch control. The Link has a few different setups for launch control and seeing that I'm a nooby to the concept I will use the very-very basic concept. I've been reading Link's help / definition files and HPA has a launch control course & webinars I will be watching/freshening up on. They have a worked example on the Link but they use a Haltech and a Motec for the webinars/courses. But I'll get it figured out...I'd like to get it setup and jack the back end of the car up and do some dry-runs. I'll upload some media.

 

finished welding and installed a 1liter lab-grade nalgene bottle for water/meth ... I'll replace the rubber-band with a velcro strap...

 

got the car out today ... spent the last few days ironing out tables in the Link...(which wasnt quite enough)...everything went well, well enough.

I ran the car a little bit more aggressively than last time. Pushed the car just past 5k RPM (in road / fuel tuning methods), I'm not sure how much load I put on the engine but it'll come through in the logs. It may have been a few psi ... nothing significant. But really happy that I was able to push the engine that high in the rev-range with no issues.

Over the next few days I'll need to further tweek the failsafes ... they are really handcuffing the engine ... to where I am having multiple RPM limits kick-in. Not only is it limiting the engine it's also lighting up the laptop with error-codes.

I'll be fixing the fuel map (based on the logs taken today) and see about getting the car out again.

 

1 liter of meth will drain quickly. I would put 5 liters at least.

 

I hear what you're saying ... I dont recall using / refilling the 5gal (19liters) all that much but I'll look into a 1gallon bottle...it might be wise to have the ability to run either or.



Reviewed the logs and didn't get into much positive boost but that's ok... I ran the car well into the 5k RPM range under light load (~25%-30% throttle)...

I put about 18miles on the car and did my best to drive the car in a manner to get good fuel log data … heres a quick snap-shot of the mixture map feature on the link … I love this feature...I think I'll have a little more work in cleaning up the fuel map.

 

So with that error will you just be able to multiply that back in or out to get the correct AFR?

 

you right-click on the cell and it’ll give you the option to automatically adjust the fuel table ... then (which I failed to do before) you make similar adjustments in the surrounding cells to smooth out the fuel table ...
