Rtek Rtek FAQ: Read first!!
Im just going off what their website says "planned" of their website
Alternative to Palm Desktop
Reposting turbo2ltr's suggestion to use the "Pilot Install" utility, for the purpose of adding RX7Logger to your Palm PDA.
http://www.freewarepalm.com/utilitie...tinstall.shtml
Works well in Windows 7, 64-bit, and doesn't seem to care what port # is assigned by Windows. (I used com12 without problem.) Just select the port # to match Device Manager.
Don't get too aggressive with the port speed. Up to 128000 bps will work (but the 256kbps setting will not).

Also a word of warning for T3 owners (and possibly other of that same OS version), this program will NOT sync at anything more than 9600. If you try it will start then just sit there. You have to lower the baud to 9600 and then it will sync.
When I purchase my 2.1 and install it, will I have to take the car to a shop to be able to tune it? Or can I just go through the initial setup myself, specify whichever size injectors I have and then go?
Is there anyway I can get the software emailed to me? I bought a secondhand 2.1 here on the forum. Email is boostaddict79@gmail.com

I didnt see this asked so here goes
Year: 87
Model: turbo II
Rtek im interested in: 1.5 or 1.7, undecided.
background: rather new at rotaries and turbocharged cars
Goal: Good, reliable, relatively safe power. looking for an additional 15-20hp over stock and i think ill be happy. dont want to run more than about 10-11lbs of boost MAX.
how is boost level controlled with this ECU upgrade? as i understand it the S4 turbo has a subpar wastegate that allows the car to overboost stock hitting the fuel cut. with the built in FCD, does that mean the turbo will continue to make boost until the turbocharger is topped out? is the only way to regulate this with some work to the housing and a secondary (manual or electronic) boost controller?

S4 ECUs don't control boost.
Yes, S4 turbos have small wastegates so they tend to creep when you have a free flowing exhaust. Meaning even if the wastegate is full open, it cannot bypass enough air to keep the turbine from spooling faster.
The only way to battle boost creep is by making the wastegate diameter larger allowing more air to bypass the turbine. If you want to regulate boost, you will need a boost controller in addition.
The FCD simply removes the conservative overboost protection built into the stock ECU. That doesn't necessarily mean you can raise the boost safely, it just means you CAN do it without the ECU interfering.

I'm sorry you feel that way.
From the first post in the thread:
In other words it's not tuned for any particular boost.
There is no limit, but there are limitations once you go past a certain point.
If these don't answer your question, please be more specific in what you'd like to know.
From the first post in the thread:
Are there changes to the fuel maps in Stage 1.x upgrades?
No. The only differences in fueling are that we allow the primary injectors to run 5% more duty cycle, and on the Stage 1.7, we compensate for 720cc secondaries. The fuel maps are not touched.

How much boost can Rtek upgrades handle?
The stock MAP sensor will only read up to 1 BAR (14.7 psi). While you could run boost pressures above that (with the proper knowledge and A/F monitoring), you are past the point that the ECU would 'know' that you are above 1 BAR. This somewhat limits the ECU's ability to make corrections and is past the point of the Stage 2 user adjustable maps (for now).

Quick question for you:
I have an 88 TII full racing beat revII exhaust w/ racing beat fcd. I also have the cork sport aluminum turbo inlet duct. Would I benefit from the Rtek 1.5. If so do I now remove the fcd and plug the boost control selenoid back in once I get my ecu back from you? Basically I send it out to you and Im good to go? I've been trying to figure this out but it's not as simple as the Cobb accessport that I'm using with my other car. with that a basically tell the accessport the supporting mods I have and it flashes my ecu with different preprogrammed maps.
Thank you in advanced, and sorry to hear that you have recently downsized.

You could benefit from a 1.5, though I have to ask how much boost are you running?
Yes you would remove the FCD.
The 1.5 has some safety and convenience features. It does not include any changes to the fuel map.
The process is: you order online, send us the ECU, we install it (typically in 1 business day) and we send it back.
