Anyone running a aftermarket chip/control module?

[jessetooslow]

I don't know to much about tuning, so I'm not sure exactly on how much work I plan on doing to my car. When I start doing mods I plan on getting a chip or some sort of control module from either Jet or Venom, anyone have any experience with these companies?

I remember seeing a thread where all they did was put a sicker on a chip and nothing to the board at all.

Sorry to be bursting any ones bubbles, but with my experience... its a waste of money on those "tuner" parts. Get standalone with wideband. Endless possibilities in tuning. There are other routes but that also depends on your attentions of using the vehicle.

Cant "chip" a mkIII supra. those things you find on ebay etc are a waste of money.

 

[Poodles]

Won't do anything...

 

[jessetooslow]

Thanks guys, I sort of had a feeling they were no good.

Very interesting. How come they don't get into trouble for this? Is their anything that can be done to the factory ECU or is standalone the way to go, its just a little bit out of my price range thats why I've been looking at a chip. Venom does make a control module.

Dude, do some research.

There are so many piggyback fuel controllers available for the MKIII that's it's not even funny. Between stock and standalone you have a ton of options.

Here are some of them (with ballpark prices):

Manufacturer	Model	Ballpark Price
AEM	Fuel/Ignition Controller	$340
Apexi	S-AFC	$125-$150 (used)
Apexi	AFC-II	$150-$200 (used)
Apexi	AFC-NEO	$350
Blitz	R-FIT	$325
Greddy	e-Manage	$360 + accessories
Greddy	e-Manage Ultimate	$650 + accessories
HKS	GCC	$450
PHR	MAP-ECU	$425
Full Throttle	MAFT	$200 + accessories
Full Throttle	MAFT Gen 2	$250 + accessories
Full Throttle	MAFTPro	$400 + accessories

Not to mention the Lexus AFM/550 cc Injector mod, etc.

Stay away from that riceboy Jet and Venom crap.

well i hate to be "that guy" but i ran a venom 400 for a while and it DID make a difference on my stock motor, wether you guys wana think so or not, i enjoyed it but i will say that they coulda put more friggin wire to the harness, it wasnt nearly long enough so i mounted it underhood

When judged by the butt dyno, it's called the "placebo effect"

 

[giterboosted]

not when it was choking and boost was flatlining top end before and after i put it in it modified the fuel to let it keep pulling all the way to redline, i had a cracked exhaust housing on my stock ct, so it dindt pull rite top end and i installed and then it did, sounds pretty good to me, i enjoyed it

 

[Poodles]

Advance timing and lean it out = fast





















...until it goes KABOOM!

 

[giterboosted]

fixed the screwed up=ness temporarily so idc, its fixed now runnin a 57 trim so its no longer on there

The stock turbo dies out not because of lack of fuel, it fizzles out up top because it just can't flow enough. Adding a computer isn't going to magically alter the physics of the turbo. It's just not capable of flowing more, and thus, it drops power up top.

You don't need it w/ the 57 trim because the upgrade allows the turbo to flow more air, and as such, will not die out as easily up top.

What about on an NA? Can piggybacks make a difference?
Does anyone have any dyno graphs for a before and after?
Am also interested to see a STOCK NA dyno printout.

.... excuse the bump

 

[giterboosted]

Glad I noticed the bump with all these ppl basically calling me a liar, but in an adult fashion, back then my carwas almost stock and I could tell a difference wether any of you like it or not, even had a friend drive the car without mentioning it at all to see if they noticed a difference, currently I'm running he whole 550s, lex afm, bla bla bla setup with a afc II, I'm making about 4-420 rwhp so I never said proper tuning wasn't he way to go but or a very temporary fix it DID work, as to the last post on here idk bout on an na, I just went header an exhaust an intake and was happy with my na

 

[turbo87targa]

I don't think many ppl mod out the
NA....the mk3 is a little fat for an NA I6

 

[dubsupra209]

yea save money and just go turbo....

 

[nick88]

You are forgetting the few and far between mines/stealth/blitz ecu's that where modified in the late 80's to whenever they stopped doing it.
