Hello everyone! I'm happy to be bringing you the 2026 California MR2 BBQ announcement! As always, the BBQ is not MR2 exclusive, as long as you have a good attitude and a good appetite, you're welcome to come! Attending the BBQ is also free, except for the cost of parking on location, for which the venue charges $6 (cash only!). The MR2 BBQ is also a potluck event. While bringing food isn't required, it is highly encouraged and appreciated. You'll even get a free raffle ticket for bringing something! That's right, we're bringing the raffle back! We will also be bringing back the popular car contest with 6 categories. One category for each generation MR2, a best in show, best not an MR2, and a fun category! This year's BBQ is being held at Baylands Park in Sunnyvale, CA and will last from 10:00 AM to sunset. You can sign up for the BBQ and see the potluck sign up at the Partiful link down below. I'll also summarize the info for the BBQ. I can't wait to see you there!

FCTuner - A Modern Apexi PowerFC Tuning Software

Patrick Lipp — Thu, 21 May 2026 19:05:27 +0000

For years, tools like FCEdit and CoPilot have been some of the most important utilities available for the Apexi PowerFC platform. While both applications brought a huge amount of functionality to the community, they are also products of their time — older Windows dependencies, dated UI systems, limited extensibility, partial compatibility issues, and fragmented workflows between offline editing, live tuning, logging, and autotuning.

Over the last several months, I’ve been developing a new application called PowerFC Tuner with the goal of modernizing and consolidating many of those features into a single modern Windows-based tuning platform.

FCTuner is a modern Windows tuning and datalogging application for Apexi PowerFC ECUs, focused on making map editing, live monitoring, AFR-based correction, and calibration analysis easier to work with. Its current direction is especially centered on safe autotuning, high-quality sample collection, VE analysis, and understanding how fuel, ignition, load, AFR, knock, and VVTi interact.

This is still considered beta software with active development and testing, however most functionality is operational. The software still requires testing, validation, refinement, and ECU compatibility verification for each new feature that's added.

Read and write PowerFC .dat map files.
Live monitor PowerFC sensor data over serial/COM.
Edit Base Map, Injector Correction, Ignition, VVTi, and Target AFR maps.
Display live Speed, RPM, Knock, AFR, load, TPS, temps, injector pulsewidth, and auxiliary inputs.
Configurable AUX analog input monitoring with converted values and units.
AFR-based fuel autotuning with Safe, Conservative, and Aggressive modes.
High-resolution AFR sample collection beyond the standard 20x20 map grid.
Weighted neighbor-cell sampling to reduce hard cell-boundary errors.
Filtering, stability checks, dwell timing, and outlier rejection for cleaner fuel corrections.
Session saving/loading for maps, autotune settings, VE settings, samples, and state.
Logged Data views for samples, AFR, knock, AFR error, and proposed base map changes.
VE Analysis tab for estimated airflow efficiency and sample confidence.
VVTi analysis framework showing readiness, sample count, VE/AFR/knock impact, and revalidation needs.
Map tracer support for live active-cell visibility while tuning.
Lock/unlock map cells to prevent manual or autotune changes.
Built-in Help/About menu with release/support links and PowerTune Assistant access.

LATEST RELEASE: PowerFCTuner
Current Version: V3.08

Autotuning the Apexi PFC - New Product I'm building

Patrick Lipp — Mon, 04 May 2026 20:09:17 +0000

So since I built the online Map Viewer, i've shifted my focus to building a piece of hardware for the PFC. It started as an idea and is now almost fully functional. So.. I introduce to you, what i'm calling, the PFC Gauge & Autotune Bridge, or the PFC Bridge. It's meant to bridge the gap between requiring a tuner, or a computer to handle CoPilot for auto tuning, or the full knowledge to tune in general.
It's still in a a testing and development stage, but it's almost ready for full testing.

What is it? It is a hand held device that plugs into the Apexi PFC and is able to Autotune fuel and ignition timing, backup your current maps, perform basic logging, etc.

Primary Features
Gauges
View RPM, Speed, intake air temp, engine temp, knock, and boost.

Fuel Autotuning Modes
Live Auto Tuning - Captures AFR samples and compares them to the InjCorrection map(converted to AFR) and then makes adjustments to the BaseMap and then once enough map corrections have been captured, it writes the map to the PFC.
Safe Auto Tuning - Same as the Live Auto Tuning except it creates a MapBackup.dat file(same format as what FCEdit uses) and makes the adjustments to that. You can then pull the micro sdcard and pull the map, viewing/editing it in FCEdit before manually writing it to the PFC.
Logging - Creates a CSV file that contains a 20x20 empty map and then logs the recorded AFR's in their respective load cells. It copies the Inj Correction map in a second workbook so that you can compare the two at a later time.

Ignition Autotuning Modes
Ignition Auto Tuning - using set low, medium, high knock thresholds it will pull timing when knock is logged. This is essentially knock control in a very fundamental and basic form.
Ignition Advance Autotuning - Will log knock values and when none is seen it will increase timing by 1 degree. If any knock is seen after this change it will immediately change the map back to the previous value.

WB02
Select one of the built-in wb02 options or provide custom 0-5v values in a text file on the removable sd-card.

How it all works(a general overview) -
Connect it to your PFC and start your vehicle. You'll first need to navigate to the settings menu. Once here, you'll select the option to Backup your current map. It will create an FCEdit readable .dat file.
Below that you'll select the option to "Load AFR Map". This will store a copy of the Inj Correction map as their respective AFR converted values. This is what we will tune the AFR's and base map against.
You'll then need to go to the WB02 screen and select your respective WB02. I have built in values for the Innovate MTX-L, LC02 and the aem uego, but if you have a different one, you can edit the text file off of the SDCard which provided an example.
you'll then want to go back to the settings menu and select Save Settings(while your settings should be saved automatically, it's never a bad idea to manually save everything.

At this point you can pull the backup.dat file from your PFC and view it in FCEdit, CoPilot, etc. Alternativley, navigate to one of the Auto Tune pages or the gauge page to view/start the tuning process.

Updated site looks great!

Thanks for the effort. The new site looks fantastic! Very happy you were able to keep the forum history too.

PolyUrethane Bushings

ManateeGuy — Tue, 22 Jul 2025 06:07:19 +0000

Whats up, looking to change out at least the front control arm bushing with polyurethane ones. I was looking at a post from Spyder chat ( removed link ) and eventually found my way here because i keep hearing of this guy dev (@dev) that sells a kit or a tool to remove the bushings easily and also maybe sells the bushings? Id love to chat with him or sm about it!

2025 Indiana Spyder Meet Saturday, June 14...

Galo — Tue, 18 Mar 2025 21:52:28 +0000

The Indiana Spyder Meet will be Saturday, June 14. My initial thought is starting in Spencer again, driving South to Bedford, further South then return to Bedford, IF the BBQ place has not run out of ribs! I will check with the owner to make sure ribs are available. IF we don't eat there, we will go to the Mexican restaurant we went to in '21. We can meet up for a nice dinner on Friday, in Bloomington IN, like we did in'21 and '24, or not.

So, there it is. For a spirited drive, sharing great roads and meals with some great people, it's a fun time. Maybe see you then!

IF "you're" contemplating being "here", "food for thought"...

Friday evening, 6-13, ALL in Bloomington IN; Smokin' Jack's Rib Shack, Casa Brava & Riviera Maya, Sakura 15 and Bucceto's(Liberty Dr location).

Saturday lunch, 6-14; Bedford IN/ Smokin Jim's BBQ & Steak House, Yamato, Pub 15 and The Rusty Gator.
Bloomfield IN/ Casa Sevilla.
Bloomington IN/ Bucceto's.

We wouldn't do BBQ both days, Japanese both days, Mexican both days or Italian both days...unless "you" wanted to.

Check them out if you want, I plan on "visiting" the Bloomington sites and the non-BBQ site in Bedford. This will give me an idea about the locations and their ability to handle our group. I'll give my thoughts, hopefully, be the end of this coming week.

That is all...enjoy!

Should this Forum continue to remain alive?

LordTakuban — Thu, 06 Mar 2025 15:41:40 +0000

I come to this forum every so often to make sure things are updated and to renew licenses on modules for the forum software. I've noticed, especially lately, that there isn't much action on the forum these days. So, I've created a poll since this forum is really by the community and for the community. I just facilitate stuff.

Swapped out the Daily Driver recently

Well, after 5 years with my STi, I decided I wanted something a bit more fun. I didn't need as much practicality that a back seat offers since I don't take kids to school anymore. The main issue I had was figuring out what, exactly, to get. Ultimately, I decided on a new 2025 GR Supra 3.0 Premium.

I am simply stunned by how fast this thing is. So far, I've only tinted the windows. And Gary Dean is going to be coating the car next week. But I have a few more mods planned. It is still a bit annoying that there is no Android Auto in the car, but I'm going to fix that soon as well.

I'm not on here much these days. But I figured I'd share the news with the few others that still frequent this place from time to time.

Goodbye 2024 and welcome 2025

I just thought I would bop in to wish everyone (anyone here?) a happy new year!

Now that the election is over . . .

Uncle Mush — Wed, 06 Nov 2024 23:39:48 +0000

I went out into the garden this afternoon and picked our firsts batch of bistro peas to serve with our celebratory dinner today. What are we celebrating, you might ask, in light of the election being over? Oh that's an easy answer! We are celebrating NO MORE POLITICAL COMMERCIALS for another 4 years, of course! 😋

The only other thing for me to report here is that I took the Spyder out for a brief cruise yesterday just to keep fluids running in the vehicle once in a while. It sure felt great to drive it again. It was a crisp fall day and I'm pretty sure my little garage queen was happy to be on the road again. Anthropomorphic? Yes. Hey I'm old and I can see the world how ever I want! 😉

So when was the last time you posted something here? Are you like me and you stop by once in a while to see if anyone is posting anything of interest?

I hope you are well and wish my spyder colleagues all the best.
