turboed tc 06

[Butters]

ok so i have a turboed tc and i put 550cc injectors in it. so when i plug up my emanage ultimate to the pnp harness it will not start on cold start. but when i switch it back to factory i can start it up and run it and turn it off and put the EU back on and it will start up. weird thing is it will not accept any retard timing to it. I think thats what i have to do to get it to start cold with the EU hooked up. anyone find a base tune for the EU with 550cc injectors? i can only find 440cc one. maybe thats my problem. anyway hit me up with ideas and suggestions that would be sweet.

thanks guys!

The Ultimate has a menu screen that you setup your vehicle parameters. This is where you would state your correct injector size. I believe the Ultimate is supposed to self-correct for that. You will not be able to adjust ignition timing with the GReddy or any piggyback that I know of. The ECM retains full control over ignition timing. Although you could share maps with another Ultimate user, it would only be setting you in the ballpark. To find homeplate, you will need a good dyno tuning session.

Was your Ultimate working fine before the injector swap or were they installed at the same time? Are you receiving any DTCs? What exactly is, "will not start"? Please define exactly what it is doing.

Well when i plug in the ultimate the car will not run at all if the car was sitting over night or day. when i go to the factory ECU and back to the Ultimate the car will start up just fine. like I plug the factory ECU in and start the car and let it run for about 5 min and turn it off and swap it to the ultimate the car will start up fine with no problems. i would like to avoid this problem with it since i really am tired of pulling my glove box down everytime. lol. i have emailed Greddy on the problem but they were unable to help me from what i was told. i have had a guy that has done multiple piggy back programming to help me but he was unable to figure it out and it was his first working with a Greddy product.

hope that help clarifies more.

Sounds like the Ultimate is not powering up. Could be tapped into the wrong leads for power and ground. Are you using a pre-made PNP harness or are you using the universal one that you have to wire up yourself? Can you verify that the Ultimate gets power when turning the key to ignition on a cold-start? Have you tried doing the swap procedure and start with the Ultimate w/o warming up with the ECM? What year is your tC? GReddy produced a pinout chart for '07-up that they incorrectly had stated was for '05-'06.
Once we determine that the power is tapped correctly, we can move forward from there.

I got a premade pnp harness from Dezod. the ultimate powers up just fine cause when trying to tune it i see where the cars fuel points is going around the screen when driving and i have a green power light lit up on the side of the Ultimate. i have a 06 tc ecu and body but 08 engine and tranny. yes i have tried to do a cold start w/o warming up the ecm but the car just cranks and feels like no spark at all but i have spark as i tested that and i have fuel as i can smell the fuel. lol.

It is possible that the Dezod harness is defective or wired wrong. The '05-06 ECM is different from the '07~up ECM. There are a few pinout differences, a different MAF sensor, and is CAN compliant. Beyond the MAF, I believe the engine controls/sensors are the same for all year models. Not sure what else could be causing your malady. Possible that your tuning map is damaged or improperly setup.

Well I did some research and found some info on scionlife from someone. They said that one of the settings from Greddys base tune is defaulted to 5v when it should be 12v. I will attempt that but I did check the wiring from the Dezod PNP harness and it seems right from what the book says to wire it up on dezods website. (wish they would of color coded them different colors then all being green) I will attempt this again and let you know what happens. Thanks,

Do you happen to have that link to the 5V/12V issue? I am wondering if that has been the cause of my issues as well.

[Butters]

I was reading through scion life and found it and one guy said it fixed his problem for it not starting on emanage. I hope it is just a simple switch.

great im having another problem now. My xp laptop crapped out on me a couple months ago and i bought a new one and its not compatible and i tried the compatible program but it just will install the driver for the usb part. i tried a virtual machine with xp but i cant seem to get that to work so a couple more days of messing with my laptop now.

[Butters]

ok well i put a virtual machine of xp on my windows 7 laptop and got that to accept the usb driver to my emange now. then i opened up the emange and switched jumper 8 to 2 and 3 instead of 1 and 2 and the car started right up. so far so good. now some tunning to do.

I tried that trick today to get a Dazzle DVC 80 digital media converter to work and Vista does not recognize a driver for it. I always seem to have the wrong patched OS. I had trouble getting mine to start because GReddy was posting the ECM pinout for the 2007-up models as that for the 2005-06 models. Their USA tech support was if no help and actually they knew about zilch about the Ultimate. I was one of the early adopters of this on the tC. You will also find out that you have no control over timing. Basically all that can be done is to chance fuel trims. There is no IAC control either. I have heard of a couple fo persons that has made claims for work arounds, but these involved some serious skullduggery to fool the ECM with H20 temp tables and such. Way too complicated for a piggyback.

[Butters]

I think it is hard as well. it will be tricky but i wouldn't mind attempting it later down the road sometime this year or next. the car has turned into more of a project car now since i haven't been in a car show for 3 years now.

Do you still need the pin-outs for your car? here is a link for you to try out if it helps:

I have those pin-outs. I actually had to school GReddy USA on the problem.

[Butters]

Thats Awesome!

[navylife59]

At the time, it sucked because I followed the poorly written instructions to the letter, triple checked everything, and talked to the tech support for a couple a couple of days before I figured out that they incorrectly listed the '07-up pin-outs as '05-'06 as the 2007 model year had just arrived. I had the same problem with my MSD Dashhawk OBDII scanner. Their tech support told me it would work on all Scion tC's. Later, after many phone calls, they realized that they wired and coded the scanner only for 100% CAN ECUs. That meant pins 6 and 14 (CAN High/Lo) would have to be populated in the DL3 (OBDII) port to work. 2005-06 are not fully CAN compliant so those pins are not populated in the DL3 connector. Lucky that I happened to have a 2007 tC on hand to figure it out and make use of it.

[Butters]

oh damn man. i guess you were the ginny pig for most of the stuff. Did it all work out ok for ya?

In a couple of weeks im taking my car to a dyno and they guys specialize in MR2 Toyota's but have never messed with a Greddy Ultimate and they want me to teach them how it works. They seem pretty excited in learning from my car. I just hope my car will be able to get on the dyno since the body kit sits 2inches off the ground.

Well, the GReddy interface software is not very intuitive and only works up to Windows XP. I had heard rumors that there was a port to Vista but have not been able to confirm yet. If these guys are familiar altering fuel maps, they should be able to figure it out. Most of the advance features don't work with our ECM. Best that can be altered successfully is WOT fuel trims.

I seem to get burned on alot of stuff I buy. That is not because I don't research it. It is the simple fact that I have been an early adopter on new product that hits the market. Let's look at my list here.

1. GReddy Ultimate - Big waste of time and money jsut for WOT.
2. Nology Wires - Complete waste on eye-candy. Did no good and damaged my OEM coil packs.
3. Axis Wheels Super Hiro - Paint job is crappy (not painted on inside). Blue pinstripe flaking off. Offset +35mm too far out and required shaving the rear fender edges (can't be rolled) for clearance even though their tech support stated that it fits no problem. Junk made in China.
4. HKS Hipermax RS coilovers - Not spec'd for tC. Just happens to fit with spacers. Front strut end-link tab in wrong position. Spring rate too weak.
5. Snow Performance meth/H2O - Safe Injection system recalled for incompatibility with Methanol. Had to send my old one back. Waited for months to get upgraded replacement. They said it was an indefinite wait and offered me the original (non- Safe Injection) controller. I opted for the exchange. After I received it, the Safe Injection was announced ready to ship. They would not let me convert back even though I never installed it.
6. Spec Clutch Stage 2. Did not install it because I had read of some failures of the hub springs coming loose.
7. PLX Devices MFD - I sunk a ton of money for this seemingly top of the line multi gauge display. It was about as easy to get a new wifi router setup and all of your different devices to work on the first try. Once I finally had all of the sensor connect and recognized by the Wideband controller fried for the 3rd damn time. It never worked as advertised, poorly conceived, and now just $700 worth of junk.
8. MSD Dashhawk - It works as advertise but only on 2007-up Toyota/Scions with full CAN OBDII port. Not the 2005-2006 tC that their tech dept stated it would work.
9. JVC KD-AVX77 headunit - Supposed to be the only headunit that offered true interface with iPod/iTouch. It worked once then stop. 2 iOS updates later and it works, as advertised about 75% of the time. The other 25% has me troubleshooting and lucky if I get it to work correctly. JVC says Apple's problem. Guess what Apple states? Ya, right.
10. 2007 RS3.0 OEM headunit - iPod interface is about worthless. Now I know why my Son would just use the aux-in jack instead with his iPhone.

I am sure there are a few more. Just too late to remember them all.
