Does megasquirt work with the gen 5? I can’t find any documented info on anyone running MS with a gen 5.
Are there any pnp solutions with the gen 5? Closest thing I can find is this https://pidashs.com/products/3sgte-mr2-celica-9395-megasquirtpnp-gen2-plug-and-playIt can be made to work, yes.
really useful info here. I'll make sure to bookmark this. thanks for your input!You definitely don't want to start with a MS PNP2. For one, it's a very old/outdated ECU at this point based on MS2, and two, you'd be doing so much wiring you might as well start with a wire-in ECU. I had one installed on my SW20 when I bought it, and it experienced 2 hardware failures in 6 months as well...
I'm selling my AEM Infinity 506 which will easily run a Gen 5 3S-GTE (I upgraded to an Infinity 708 with more I/O for nerdy experiments). I was running my Gen 2 3S-GTE with coilpacks and a Gen 4 MAP sensor (plus other stuff). It has a good feature set of I/O, and I documented the wiring harness here for a Gen2. It would be easy to look at the BGB and find your harness wire that corresponds to that function using that as a guide.
The Infinity 506 has I/O more inline with the upper end Haltech/mid-level Link ECUs, so it can do things like wheel speed traction control, has a very fast onboard wideband controller, plenty of temperatures and inputs to run your engine and allow you lots of control over it.
IMO, the issue with low end Haltechs is the I/O is severely constrained, and by the time you get a wideband on it and get things running nicely with user input switches, AC running nicely etc. you're at a fairly eye watering price. To put it in perspective, the low end Infinity Series 3 has more I/O than the top of the line Haltech Elite 2500 out of the box. The Elite software is easy to use in some cases, and kind of difficult in others (my opinion). Link is better priced on features, but I didn't like the software when I poked around in it for a bit.
I personally think the AEM Infinity Tuner software is very easy to use. Basically all the underlying setup is done in an easy to use wizard that updates the layout, then you use the pages of those controls to change values.
The 506 will do flex fuel, different octane fuel/ignition maps, different traction control settings etc. All easy to setup.
Honestly, if I didn't do AEM Infinity again, I was pretty close to either a top of the line Link (but software was a turnoff) or a MaxxECU which are priced competitively and seem fairly feature rich.
Was thinking $1100 shipped for 506 + 80 pin connector. But if it goes to an MR2 guy, I’m thinking $1000 shipped for the above. I can also get you other AEM parts for a good price (I have a wholesale account).really useful info here. I'll make sure to bookmark this. thanks for your input!
And how much would you be willing to let your infinity 506 go for? Just wondering.
I plan on getting everything professionally tuned to avoid any mishaps. As much as I want to dive into the world of tuning, I think it's something best left to the pros.Was thinking $1100 shipped for 506 + 80 pin connector.

I would suggest adding a fuel pressure sensor (fueling is accurately calculated on actual fuel pressure, which does vary for most setups), and at least one switch/12 position pot to control boost/maps. I also have a 3 position switch for traction control slip target (wet/dry/off). Reading my build thread in the SW20 section (search Turquoise Awesomeness) covers a lot of these details.
But once you learn to tune your car yourself, it’s really liberating and you understand the car way better. Warning, it is a lot of time to do a super clean tune. Probably 20-30 hrs of time for a bunch of tune/test loops, and there will still be room to clean little things up like starting, throttle transients etc. I personally enjoy it, but don’t expect it to be a 20-30 min process then you’ve got an OEM level tune.
