Has anyone here sent there computer off to Jet and had it reprogrammed??
Is it worth it
Do you notice any difference?
i have a 1993 toyota truck 22re

 

Yeah Buddy I did it runs like tuner car now. It hurt gas mileage a little probably because now I keep my foot in it all da time

 

hey CJ, were you running stock when you reprogrammed?

 

I was thinking about this also, but doesit justify the 300 dollars?

 

ya same here, i was just worried about it working right when i got it back,
what all do they program to make it better?

 

EDIT: This is in reference to a JET Piggyback Chip, rather than an ECU reflash which I didn't know was available.

JET chips are a waste of time, all they do is add a resistor inline with the AFM to make the engine run richer. You could obviously do the same thing yourself if you're so inclined...

You might experience a very mild increase in power (and subsequent decrease in mileage), but for the most part they're piles of

 

Ummm.. I think you're confused Brian, or there's another JET option out there.

I'm not a fan of the JET stuff either, but what they're doing is modifying the fuel and timing tables in the ROM. They kick in a few degrees of advance and lean things out a hair. The combination "should" net you some power.

The issue I have with them is that it's a hardcoded change, you can't get in an tweak it; plus it's VERY expensive. Given that you have to send them an ECU, the work they do only takes about 10 minutes with about $30 worth of programming hardware.

It's a HUGE rip off.

If someone is looking to dial in some advance, at LEAST spend the _same amount of cash_ on an PerfectPower SMT6 or a SplitSecond FTC1. That'll let you play with the numbers on your own.

 

well im open for anything,, i just thought Jet was the only thing i could do
couldnt find any other chips or programs to up my power
it is in a 1993 Toyota Pickup 22re

 

Talk to dcg9381 on here. He's working with Megasquirt EFI for toyota(specifically the 22RE(and T).

It may or may not net you more power, but for the same price as getting your computer JET flashed, you get a fully tunable (and loggable) EFI system.

 

If it is a completely stock engine then changing up your fuel and timing values wont give you much more horsepower, and will probably decrease mileage... but if you're modified, like a cam, intake, exhaust then modifying fuel and timing for that will make more of a difference. Check out some of the tech pages at SDSEFI.com They make programmable efi systems and even if you dont use their system their tech pages are pretty helpful... may give you some ideas what kind of power increase you're looking at.

 

It's not gonna give you any gains, not overly noticeable ones anyway.

If your truck is stock then put on a freeier flowing intake, header and exhaust system.

 

Megasquirt eh? I had that on my RX7. Good standalone but you need a laptop or a really reallylong cable lol

 

Different engine, but I've been _right_ on the edge of going with a MegaSquirt system for a while. My latest brickwall came from when I found that the MS ignition module only support a single-coil system.

 

Programmable systems work great. Thing is they have to be programmed FOR the motor/modifications and that requires dyno time. I have ZERO faith in the jet chip.


Midiwall,
That's not correct. Megasquirt can support multi-coil (coil on plug) ignition systems. It's come a long way in the last 2 years.

 

Yeah, you've mention that to me before, but when I got the urge to again do this, I found:

http://www.megamanual.com/ms2/Ignition.htm
http://www.megasquirt.info/MS%20FAQ.htm#ignition
http://www.megamanual.com/ms2/indexright.htm

In which all talk about support for only one coil...

 

Interesting.. I just read in the MS-II manual that it doesn't support multiple coils.
As an "open source" (sorta) project, sometimes the docs lag the functionality.

MSnSE (Megasquirt and Spark Extra, MS-I) will do multiple coil support. I typically see this in the "COP" or Coil On Plug configuration:

http://www.msextra.com/manuals/MS_Ex...ual.htm#2coils


My understanding is that the latest version of code can control up to 6 spark outputs.

Is it coil on plug that you're wanting to do?

 

Hmmm, okay... time for me to come out from hiding on the forums over there and ask.


Yeup. The 5VZFE 3,4L is a 3 coil wasted spark ignition with 2 missing teeth. So I'll need 3 spark outputs.

 

Ignition is probably the most difficult thing to setup with the MS system. Remember that you can always throw on a crank trigger and use EDIS, which is well documented. I dunno if anyone has done a 5VZFE yet as I can't find a reference to it.

 

neither can I, and I've been looking for 3 years. I may just have to be _that_ guy.

I'll look into EDIS as well.

Thanks man!


(sorry for the thread hijack folks)

 

hey Mark, I tried to PM you but it apparently didn't go. as your site is down, is there any way to get a copy of your ECT mod page?
thanks.
