This weekend was a busy one. Scott Clark and I decided Friday to make an appointment to tune my car Sunday.
So of course, I had some things to finish up in a short amount of time.
I cut my new speedometer cable to length and got that installed. I thought this would fix the last of my trans leaks, but turns out the governor delete plate is seeping a small bit. Just need to pop it off and silicone all the way around it according to the guy who built my trans.
The thermoswitch for the trans cooler fan out back is seeping some too. Not really sure wtf to do about that because they specifically say in the instructions to hand tighten it, and to not use tools. Maybe I'll try cleaning it real good and putting a bit of RTV on the base of it.
I got the turbo drain gasket replaced last minute which solved that issue.
I also need to get the catch can on tonight, it has quick connect fittings for the sight tube, one is broke and those fittings are hard to find!
We loaded the RX7 up and headed to the 402 Dyno outside of Omaha, NE. Scott Clark and Jered Klug were awesome. They both came in to meet up to tune the car on a Sunday.
The only issue we ran into was the wide-band reading on the laptop, on the gauge in the car, and the dyno's wide-band were all reading differently
I didn't have the terminator plug needed to program the LC1 in the car, so we had to cut the end off the cable and wire the red/black wires together to "terminate" that end.
Once we got the LC1 reprogrammed and free air calibrated again, everything read exactly the same.
Scott started with idle tuning, moved onto startup tuning, accel enrichment, etc etc. The car idles rock solid at 850 with a closed loop idle. It no longer lean spikes or hesitates with a hard stab of the throttle and it comes back to idle after a hard throttle hit perfectly now.
He moved into load and driveability testing, and finally into some WOT tuning. We were only making pulls to 5200/5400 RPM's to save the converter and my tires. Rubber was flying everywhere The tune is also setup for closed loop WOT as well! It can adjust WOT fueling based on a number of factors, we added 3% extra fuel to Cylinder #7 since that cylinder is know to have problems and set it up to be able to individually pull spark per cylinder, up to 5* if necessary. The end result was a fantastically tuned, safe car that I'm totally happy with. The car also stayed pretty rock solid at 200-205* Coolant temp the entire time, even on some back to back pulls! I just need to get it switched to e85 so we can add more timing
Because of not making full pulls, coupled with Jereds dyno (brand new Mustang) reading numbers much lower than even Chad's dyno (Mustang), any numbers I got don't really mean much. I will say that it made over 400whp at only 5400 rpm on the ultimate heartbreaker dyno IE: he said a car that made 500hp on chads dyno read 60 hp less on his!
Next up: Wiring in my launch control and boost control.
I also hope to have the traction control on, wired up and functional by No Prep in a month.
Just need to change the oil and plugs out tonight and I should be out cruising around.
