What have you done to your Tacoma today? 1st Gen Edition

I bought one!!!

 

this is for the lc ?

 

The only thing missing here is the evil laughter. That sounds like fun.

 

Nah, taco for now. Depending how I like this compared to a Haltech ECU, I'll decide if I want to order another for the LC.

 

A pittance, only $800. Same feature set as a $1300 Haltech though. We shall see how well it delivers. The examples of vehicles running off one is extremely promising.

 

I looked into ProEFI for a few reasons. 1. It can fully control the A340E and 2. They can remote tune since I don’t have a dyno nearby. But was $3300 without a screen.

If FuelTec ever adds the ability to fully control the A340E it sounds more attractive since it can be fully tuned through the screen/cluster unit.

Was the ProEFI ever a consideration for you?

 

No it wasn't, the feature set looked acceptable but the support from other tuners and protuners is minimal in the US. This megasquirt gold box I got can be had with a microsquirt included in the same box to be used as a trans controller (talks through CAN bus) for the A340 or as extra I/O. I opted not to get that because I'm manual and I didn't need more I/O for a 5vz. But for my Land cruiser I'll probably opt for it since that's an auto. In the US most tuners will be familiar with Holley (or FITech), Haltech, MegaSquirt, or Speeduino and with this sort of uncharted territory it's best to choose something that has a group following to some degree because the shared knowledge is paramount if you're not paying someone to do it all for you, plus on any aftermarket ECU... There will be ongoing tuning, it's never Done so to speak haha.

Thankfully the 5VZ is sensor wise, and ignition wise, very similar to a Supra. So I have lots to work with, though my base map will be entirely my own since that doesn't exist yet :/ And in your case, the a340 was popular in lots of cars and trucks and is extremely simple to control, so most trans controllers will be able to.

 

If it's legal for use there, it ain't any fun anyway. Case and point, the TRD supercharger without the barely functional 7th injector kit (not legal in CA).

 

So essential because most states have an Emissions every year or two you would have to take it out
and install the OEM to pass Emissions? Then reinstall it?

I do that with the methonal kit but all you have to do is just unplug the wires and remove the nozzle =5 minutes or less

 

please make a post when you get it in. I’m very curious about these

 

I don't know, most states aren't very strict anymore besides CA. I live in WA, we don't do emissions, neither does Idaho, Montana, Wyoming... Etc. My setup that I'm working on would pass WA emissions back when we had it. But it's just a sniffer test. Just program it to run a bit lean and she's good haha. Catering to emissions, is something you have to decide to do yourself. I won't convince you one way or the other. I just know that stacking more devices on top of the OEM ecu doesn't produce ideal results and has way more physical crap I have to stay on top of to produce half ass tuning results. Rather just have it run right as is with boost, and an aftermarket programmable computer can do that

 

I'll let ya know. But it's one of those projects, you're either into it or youre not. Paying others to do it adds up insanely fast. I've been researching for years and I'm still not 100%, but I'm at the point where I'm only gonna get the last few percent by doing

 

They don't eyeball your ECU in CA to make sure it's still there or something, the visual inspection is literally just them opening the hood and taking a look. That said...if you run this aftermarket ecu and ditch your MAF and stock emissions equipment then yeah you'll definitely fail lol.

I've passed emissions with the 7th injector and piggyback installed twice now, they don't inspect every nook and cranny of the truck. But anything glaringly obvious (like a turbo or non CARB approved intake etc) or anything that triggers a fault code will equal a no pass.

Some smog shops are worse than others, the one I go to is pretty relaxed. Since I go there every time I'm in and out in 5 minutes now, the first time took awhile longer.

 

What if you no longer have fault codes haha. This thing kinda replaces that, it can tell me under no uncertain terms what's wrong if something is when plugged into a computer.

 

I would be curious to see if it would fly here, if someone ran that and kept the MAF and cats in place but adjusted less visible things and didn't throw any codes...I could see it working.

Might also depend on if your truck is old enough to require the sniff test or not...I forget the cutoff but some vehicles have to get the tail pipe plugged into a machine and that might pose more of a risk. Luckily my truck isn't old enough for that, I've heard of guys with no fault codes getting a no pass because the tail pipe results were just out of spec

 

Our smog rules are a pain the ass sometimes but I feel worse for the guys in MA (?) that have the really strict safety inspections where their lift, tire spacing, aftermarket bumpers etc can make them fail the state inspection. Kind of surprised we don't have the here to be honest, not that I'm complaining. You can literally have no brakes and CA doesn't care, but god forbid your air filter isn't CARB approved lol

 

I don’t think any standalone is capable of spoofing all of the factory information via OBD2. Wouldn’t this be huge issue?

ypu could always just swap back to the OEM ecu for the test though. I’m sure plenty of people do that.

 

Haltech does, some of the Holley ones do too.

 

Fun times

 

This gets hard unless you're leaving everything stock besides the computer. Since you'll have other sensor in play or different injectors. You can actually have both computer connected and only have the aftermarket one control and have the OEM one there to spoof emissions shit
