Upgrade ECu: Auto

I know that the only system that will work well with Auto's is teh Power fc, but eliminates the hold feature...i don't really mind. I was wondering if there are any new systems that ahve recently come out that will work with Autos. Or any old ones that i am nto aware of.

Peter Farrell (PFS Purple) will work and thats about it. Its an old EFI piggyback system with no support. I called AEM, and I also called several rotary shops and the PFC or the AEM will not work . you will loose the hold features and the trans will not shift right. you can run any system as a piggyback but why would you spend the money and only get to use 1/2 the functions. just keep the boost at 10 psi and run all the bolt on upgrades. speed your money on 4.33 gears in the rear end this will let you put more FWHP to the tires.

Jeff your sayign not to buy any system? But that will be harsh with boost creep ..etc. I searched and read your psot a whiel back ago when you had the same problem. So i'm guessing you researched and came up with PFS is the only suitable one?

Ok i will correct one thing, The Guys at Rotary Proformance in Dallas Texas has put hundreds of PFC in to FD autos, what you have to do is get a Auto tran Controller from Petti that controls the Auto in the same way that the Stock ECU&Trans Controller does.

you didn't search did you? any piggyback, a standalone piggybacked, a standalone with the trans ecu stranded (no hold), or a "reprogrammed" stock ecu.

WHAT??? hundreds??

Come on.. I would of heard about this if someone acturally got PFC to work on auto tranny.. and especially "HUNDREDS" of auto FD's.. And if this is true, I guess all the people who did auto to manual swaps are idiots!! If this is true, I would like to do my manual to auto.. or go buy an auto FD... I need some facts!!!

How well does it shift and if there are any issues??
How does it work with stock gauge cluster and such??

Quick search I found this.

https://www.powertraincontrolsolutio...el_harness.pdf

and this:

http://www.powertraincontrolsolution...u_product2.pdf

So, how does it work?? how does it interface with PFC??

3rd gen rx7 has an Automatic Transmission R4A-EL electronically-controled,4-speed automatic.

I'm very curious to what this Programmable Electronic Automatic Transmission Controller could be used with PFC.. It seems like it will just control shift points..

It does just what it says it does. It controls every aspect of the auto tranny. it does this without communicating with the engine ecu. It doesn't have to. You can program it to operate in a mode similar to "hold", even to illuminate the "hold" light. You can program modes for snow, or rain. You can even program traction control. In addition to shift points you can also do line pressure which affects shift speed and quality. I really can't go into all of the features of this, but there are many.

Dude where have you been? While "hundreds" may be an exaggeration, certainly there are a lot of autos running pfc's with no problems. I ran that way for over a year. I think there are some lockup issues running like that, as the car ran a lot hotter before the PCS TCU. Still it ran, and ran well.

The PCS TCU gets rid of the annoying flashing hold light, offers realtime display of ATF temp and other previously unreadable sensor output, is fully programmable, allows for data logging, etc. Think of it as a datalogit for the tranny ecu. It also can integrate with the "shrifter" (www.shrifter.com) to provide a shift from the wheel experience.

So why would anyone (myself included) swap to a 5 speed? Well, it's a different experience. Plus the swap is a LOT cheaper by far. The auto tranny in it's stock form, also will not handle a lot of power. Why pay all of the money for a custom auto solution that will break?

There are some advantages to an auto. Drag racing for instance (well once you get moving that is), no missed shifts, better traction, plus the boost stays on. It puts you in the seat and keeps you there.

We're all aware of the advantages of the 5 speed and I'm not arguing against it (no flames please), merely pointing out some of the things you asked about.

My auto cluster works fine with the 5 speed tranny-so I'm sure the reverse is true. There are no issues with the TCU and stock gauge cluster. The only thing I noticed is that the hold light quit flashing!

Shifts are a bit rough (clunk). the stock TCU and ECU "talk" and the ECU cuts torque during shifts. You lose this with an aftermarket solution. Didn't bother me at all.

Hey Ruffryder. the best system to use for the auto and not have to purchase an extra controller for the trans is the PFS (purple box with pink nine software). this is what most auto FD's are using with good luck up to about 350 HP. which is about max for the trans. but this system is out dated and EFI will not support it or repair it . so if you find one for a good price try it, but make sure you get the controller/ keypad with it and have it tuned by a rotary shop with all your bolt on mods. don't use the # 3 setting unless you use race fuel to avoid detonation. I think thats how people were blowing motors ( improper tuning and low octaine fuel). If I can find one for a good price with pink 9 software and stock PFS maps I may try one. But for now I'll stay at 10 PSi which is what the stock ecu can handle.

HKS PFC FCON with FCD is a piggy back which keeps the hold function. Ran this for 4 years, can upgrade mod chips for $50 from HKS. I have it still, but have converted my auto to manual. It can handle all the bolt on's, it can make the car run as much fuel you want to dump, but i don't think that system alone can adjust timing. I picked up my system for 250 with FCD. Run 12 on low boost and 15 on high setting ,greddy profec B, ASP SMIC, Full exhaust, no cats, Intake.

Ive got the PFS purple with pink software (allows air fuel adjustments, timing, and boost levels settings). The system also allows you to set up 3 on the fly swichable power settings. Add a 4.10 rear end, downpipe, catback, cold intake, and you have an auto fd that kicks ***.

for the auto bashers - take note. I love 5 speeds, never owned an auto, but most of the manual cars that are for sale or eventually come onto the market are beat to **** and look like **** and need everything fixed. My auto 7 looks, smells, runs, and feels brand new (interior and exterior). I would have to say that it is one of only a handful of 7's in the USA with very low mileage and still in pristine like new condition. Ill just have to suffer with the auto.

Hey Chuck. How do you like the PFS system ? is it worth getting. I've heard both good and bad , but most guys running auto's seem happy with the system as long as its pink 9 software and stock PFS maps. my car is in the shop now getting 4.33 gears in the rear end plus DP,Catback, Efini Y Pipe, and fluidyne radiator. I also installed a custom SMIC. The shop changed the wastegate pill and they said they are seeing a 10-8.5-10 boost pattern with no boost creep. so I may start looking for a PFS with pink 9 to finish the job. let me know what you think of the system

AEM will work. I haven't done it (I love me some stickshift), but i've definitely seen the auto-tranny setup menus on mine.

From what I've read (since posting earlier), AEM was not able to get the HOLD function to work.

jeff,
i like the pfs system. its easy and convenient to use. only problem is no manufacturer support and limited info re: configuration. there are a couple of sites on the internet that provide a good basis for understanding the function and configuration of the pfs.

i believe that the safest and best results could be achieved using a device like the innovative wide band system with datalogging and speed logging options (inexpensive and comprehensive) in conjuction with the pfs pmc.

there are very good and highly affordable deals on these units as compared to other systems currently available.

ive done similar upgrades as you are doing and i am definitely happy with the performance. the change i did to a 4.10 made a huge difference , but a 4.33 will be awesome. from a rolling start, the manual guys would be hard pressed to keep up. if you track it, i would be interested in the numbers you achieve.

have fun, keep the rubber side down.

Hey Chuck. I should get my car back from the shop in a couple of weeks. I am going to start looking for a PFS system to complete my mods, and get the car tuned. let me know if you find a good system for sale. I can't wait to road test the car with my new mods and the 4.33 gears. should make a big improvement. I'll let you know how things turn out
