Rtek7 ECU Upgrade
 

I was thinking of getting it. Anyone here using it? Do you like it? Thanks..

I can't speak for how it works since it is sitting on my desk next to some 720s waiting to be intalled but the Digital Tuning guys were great to deal with. I'll be installing in two weeks and I'll post my experience.

Cool.. Thanks. You ever sell the vert?

ive checked into this, and the only complains about that ECU are due to user error or pre-existing problems with your car.
I havent seen anyone with problems with the actual chip itself.

No, poor thing has been slowly raped of parts for my TII but I will build her back slowly and probably keep it.

oh ok..

I installed my Rtek v1.5 yesterday. Fuel cut is gone and I couldn't be happier! Now I need a Profec B and a FMIC.

I have the 1.7v. Gotta like the flood clear.








Hint hint, version 2.0.

Release version 2.
[/little voice in head]

I have version 1.7 and am loving it. I can push 12psi all day without worrying about blowing my engine because of excessive timing and/or fuel starvation. However, I still haven't been able to get the ecu to unflood my car.

With the Rtec do you not need a SAFC??? Im getting a rebuild and I dont want to blow it but Im on a budget....I have a 2.5" turbo back Exhaust and a FD fuel pump but stock injectors so I was thinking of getting the v1.5.....
Thanks

Is that a complete ECU or just a chip and how much will it work on S4 and S5 engines?

The 1.7 NEEDS 720cc secondaries. An SAFC could be used to fine tune. The rtek is just a chip, it replaces the stock EPROM. 1.5 has a DIY option, the 1.7 does not.

Only works with S4 TII. www.pocketlogger.com

but what im thinkin is will the Rtek 1.5 be enough with the mods to not blow the engine??? I can either get a Rtek or a SAFC I dont have enough for both cause of the rebuild costs..

i just sent payment for mine today and will be sending my ECU out tomorrow. i cant wait to get this back and see what's if anything feels different. i really want it for the timing controller and fuel-cut, but the other options are also good to have.

Got mine its pretty nice

got mine installed and i do enjoy the full throttle= unflood thing.....cant really tell u if the ecu is working to the fullest since i cant boost nor can i go above 4krpm....some people have had results with better exhaust note...but personally...i didnt seem to hear a difference...the facoty duty cycle is also raised as well as the lowered secondary kickin rpm....i do notice a umph when im around ~3500rpm......i only hope that it wont kick in while im cruising on the highway

i wonder if there is any dyno charts of this b4 and after installation just to see if there's much improvement in performance or can we call this a safety feature

there's news of a Rtek 2.0 around the corner.. if u haven't bought one yet.. maybe u should wait it out a little bit longer..

so if do nothing but put 720's and the Rtek with no afc, and then raise the boost to say 14 psi will the ecu still be able to add fuel and compensate for the additional air? or do u HAVE to have to AFC to use the 720's and the Rtek is only there to compensate for the low fuel trims?

so the Rtek would also mean u could up the maximum size of the secondaries that u can use with an SAFC II as well right?

I have the 1.7 and push 14 psi with no problems(so far). The 1.7 will run 720cc 2ndary injectors with no fuel controller just fine. Iv'e had mine installed for over a month now and am very satisfied. From what I've read about the R-Tek, I would hazard to say that the 1.7 would probably support boost pressures in excess of 14 psi. However, with the stock IC and Turbo your intake temps would start getting danerously high above 14psi.

I had to choose between the S-afc and the R-Tek and I choose the R-Tek. All the AFC does is lie to the ecu. The S-afc is not going to change the fact that the stock ecu will not retard timing above 9psi. That means if your running anything above 9 psi on a stock ecu,(even with an S-afc) your timing will be excessive which could make your motor go pop.

The R-tek also is easier to install, requires NO TUNING, retards timing above 9psi, and has a bunch of other helpful feature. Ohh, best of all, the R-tek is cheaper!!!

Just my 2 cents

So what are the rimors about the 2.0?

Currently I have the V1.5 in my car. I've put over 20k on my new engine with this ecu.

I've never owned a TII so I don't know what fuel cut is really but I don't mind :D

Currently I can tell of a kick at the injector turn on in certain situations(most commonly 0psi/0vacuum load driving). I don't notice it that often but Yes I am stuck right at that rpm the secondaries turn on during highway driving.
I've done most grounding already to help remove this problem.

I plan to upgrade to 720's soon but I might hold off if 2.0 will handle 720's plus some extra stuff.

yep 2.0 will handle 720's or 550's with built in fuel correction of up to +/- 15% (basically a built in safc) as well as datalogging for just about every sensor the the stock ecu sees all from a cheapy palm pilot.

Where can this rtek be purchased from. I dont think I caught it mentioned in the thread yet (Or the other thread linked).


TIA

hey hondahater, you gotta empty your mailbox, I can't send you a pm.

any word on when the 2.0 is comming out????

what he said

Look on the first page. I posted it.

You can get it at http://www.pocketlogger.com

haven't heard of any dates as to when it is comming out but I heard henrik has been testing it for a while now and is supposedly on the last part of testing and then it's onto production. Here is a post from him a couple of days ago on teamfc3s.org.

"The logs were done with a 2.0 prototype which I've been
running and tweaking for the last couple of months. I just
ordered what should be the production boards and once
those are tested, its then on to final test, so yep its been
a long time but its close.

The VE table was just an interesting thing to do, it measures
how efficiently the engine "breathes". Its the ratio of actual
airflow to theoretical airflow. 100% would mean that the
engine injests the equivalent of 1.3 litres of air at the current
MAP reading per rev.

for the hole thread go here http://www.teamfc3s.org/forum/showth...threadid=41228

i have a 1.5 and i love the built in fuel cut defenser, i hate cluttering up my engine bay with fairly useless devices...

the Rtek is mainly for protection but it does lower the secondady staging to 3500 RPMs so it does give you a longer power band at the sacrafice of fuel mileage.


my opinion: it is well worth the $95-125 for it.

I've got the 1.7 - no complaints! It runs the 720 secondaries seamlessly and the flood clear is a nice feature IF you ever need it.

Version 2.0 will allow the user to select between 550/550, 550/720, as well as 720/720 primary/secondary injectors.

We will also be releasing an Rtek7 v 1.8 chip. Version 1.8 is exactly like version 1.7, but made for users that have 720 injectors for both primaries and secondaries.


im sooo glad the S4 guys can have something this good..

holy shit! I never knew that! Fucking shit! I just got rid of my 4 720's lol. oh well. Live and learn, live and learn.

will there be a trade in dicount offered to upgrade to V2.0???

i dont see why not, its been that way sence day one.. i just got on the wagon and if they drop it in a month or something and dont do a trade in dicount offer to upgrade to the V2.0 that would SUCK LOL.. .. ..

I wish the V2.0 was out already!!!!LOL Im getting a rebuild and from what I have read new rebuilds flood sometimes the first couple hundren miles, the unflooding would be great but I dont have the money to upgrade my injectors yet.

Did anyone ever come to a conclusion about whether the 1.7 would be safe to run for people using the old GSL-SE (I think?) injectors as secondaries? If I remember correctly they were tested at about 680, but in the thread about it nobody seemed to have an answer as to whether they would be OK to run with the 1.7.

There is not that big a difference in flow but from what little I understand about it there may be differences in duty cycle too. Is this true? I have to admit to being pretty clueless about it myself.

im holding out for V2.0 but i wish it would come out already

GSL-SE injectors range from 680cc to 750cc, so if you get a hold of some, I would send them to wwwrceng.com or another place like that and have them flow tested, if they are less than 720cc I wouldnt use them. You never wanna run 100% duty cylce, although it is somtimes ok to run 100% with side feed injectors. Which is why I want FD primaries lol.
