^ Very cool Elliot. I look forward to seeing the tuning process. That should be of interest to all.

I keep getting asked about the wideband communication with the FD PnP ECU so we've put this together;
The spare / external in 0-5V isn't available on the FD PnP ECU because it's used for the oil metering feedback. So they have to have a 0-3V or similar signal that can go into the OEM signal input, but even then it's not the right way to do it. The right way to do it is to input it via serial. We support the AEM serial protocol, but it's not that good compared to the Innovate. The main reason being that the Innovate tells you when the sensor is cold / damaged / etc, so the ECU can go into open loop mode. None of the other aftermarket WBO2 sensors do that; it's as though they just never expected people to use them to run closed loop; they only expected them to be used for monitoring. That's why we say go with Innovate Wideband. If people want to go against our recommendation then they're welcome to; they can wire up the serial output of the AEM to the serial input on the ECU - the AEM as far as I know doesn't allow you to reprogram the output to 0-5V. If you want to use EGT sensors, there are no spare inputs for this on the PNP. You need to use the TC-4 from Innovate and connect this in via the serial port. You can daisy chain a wideband sensor and a TC4 (handles up to 4 K type thermocouples) into the one serial input. No wiring at the ECU. |
i am looking to switch to this ecu. i have a zeitronix wideband zt2 logger with dual egt. will the serial connection work to send not only the wideband info but the dual egt data to the ecu as well? i understand that there is no provision for failed sensor ect like the innovative. thanks in advance

kris Kris, We haven't tested the EGT on the ZT2. Adaptronic implemented the ZT3 protocol as described to from Zeitronix, but that only has a single EGT channel. We will ask Ziggy what the difference is with the ZT2. With the TC4 / MTXL, you connect the serial out of the MTXL into the serial in on the TC4 using the cable part number 3812 (4-pin to 2.5mm). You then connect the serisl out of the TC4 into the serial in on the ECU using their 2.5mm male to male cable (comes in two different lengths). Don't connect them in the other order; they need to connect in this order with the MTXL on the end. |
so what are people's experiences thus far with these? i can't be bothered filling out this paperwork unless it's worthwhile.
i'm not referring to just plugging one in and watching the lights flash or the engine running on its own but the end results. it looks like a great alternative to the PFC for the FDs but i mainly build FCs and staging now towards the RX8s since the older cars are dying off. does this handle all fuel capabilities of the stock RX8 computer and has it had any issues within that 'piggyback"? i've got a lot of customers wanting FI renesis modifications done and that is the next step in evolution figuring out a way of keeping the 8's rather stock but allowing ways of tuning for boosted applications easily(not a fan of the Cobbs and their bullshit marriage system...the 8's are expired and there is still so few alternatives to date even almost 10 years after they were introduced). |
AFAIK this is THE renesis piggy back,, the only one that when setup as directed that will accurately drive all the manifold switching,, leaving the stock ecu to to the flyby wire throttle
( basic select set up as piggyback ) |

The S1 Rx-8 ECU is the only computer I am aware of that will not throw check engine lights, and gives you full control of fuel, ignition curves, and intake valves. The OEM PCM as mentioned is just there to communicate with the dash, chassis harnesses, alternator, throttle body( and therefore idle control ). I've personally tuned several, and sold 30+ to Rx-8 owners/shops who have all had 100% success rates. Below is an example |
nevermind on the zt2 for egt i was going to use a user input to read the second channel but it looks like that wont work. innovative it is.
|
The important thing to remember is that this is not an interceptor; I have taken plenty of those off cars in the past to put on proper ECUs because people try to use an interceptor to take the factory ECU out of the parameters it was designed for. Occasionally people ask me to design an interceptor because they want an alternative to the one they're buying currently, but it's really hard to justify because people will use it on these kind of applications (FI on an NA engine with an NA ECU) and then complain it doesn't work for them... so that's why we do it this way.

Cheers! |
i have a signal conditioner already - does this mean we could read both through the zt2 to the ecu then? if not its not a big deal i have other uses for the zt2 in other cars.

I know we spoke about this ECU and i am almost ready to order one, are they in stock? and what did you mention i needed for running E85? what would be the total cost for the sensor(e85) and ecu...
|
thanks for all the help!! i am now a proud owner of one of these ECUs :) anyone want a slightly used power FC ;)

If you want to run flex fuel (ie E-Anything - with the ECU automatically changing the tune based on the ethanol content) then you just need the fuel composition sensor. We get them from Zeitronix - they sell the sensor + cable together. They also have a display, but you don't need to run that (unless you want a display in the car). We can use either the Siemens sensor (as used by GM) or the Continental sensor (rebranded by Zeitronix, Haltech, etc).

Yeah, i will be adding one of these... I would like the flexibility to run E85/E98 or any variation without worrying about it.
I got the 440 unit and have a lot of wire management ahead of me but it just makes it that much more fun. |
We've got some new firmware updates coming soon, with some new features of the Select E440D and Plug in Models!

bump

Looking at the series 6 each as an upgrade from my aem ems series 1. What do you think is it worth the upgrade.
|
It really depends on what you are looking for in terms of an upgrade.. I am pretty sure the aem s1 does not do flex fuel control, self tuning or ve tuning( which the adaptronic does). If you are after quality and continued tech support you will definitely get that with the Adaptronic. Units are in stock.
