If its so easy then why can they not get it to work. Andrew's comment was it needed to be flashed with the version thats flashed for the supercharger. Now whether this is correct or not...don't have any idea, just relaying what is being told to us. I can certainly give you Andrews number Travis if you would like to call Andrew and explain how easy it is....and see what he tells you...


This has rev limit has been the only real hurdle so far, so would I switch the stand alone Hydra out for the AEM because of the rev limiter......really??

Its wired with a plug and play harness....just like your AEM

What was also told to us was that everything depends on the year, and that they changed from the rev limiter closing the throttle, to spark cut and that it would only work on the 07+ models.

Guru I will send you the datalog hopefully tomorrow and see if you can help with the issue.

The frustration to me lies in the fact that we have people on here that seem to have done it but the freaking tech guy for Hydra says it cant be done

 

Its prolly some stupid setting thats been over looked.

Like Guru said if the throttle isnt closing then its something in the hydra cause it does all the fuel and spark....not the oem ecu.

 

Yeah that is exactly what it seems like...just wish we could find that annoying bastard setting and fix it

 

watching and GL on getting this figured out man your tC makes crazy power!

 

that, or you may just have one thats malfunctioning. what's hydras warranty like. would the swap your unit for another one?

also i think i read that you are using 550cc injectors??? im on a similar set-up with a return system, 650cc's, and 100% meth injection, and im at almost 80% duty cycle at 19 psi. maybe there is some fail safe on the hydra that wont let you raise the rev limit because it thinks you will run out of fuel. have you tried at a lower boost. (just throwin guesses out there)

 

I was comparing the 05-06 to the 07+ in terms of ease. Supposedly it's easier to do on the 05-06 than it is for the 07+ since their revlimiter kicks in differently than our year tC does. Ease in terms of tuning to do it with a Hydra, you got me bro. Don't own a Hydra of course. Wish I could do more, cause ready to see her fly at the track.

I'm sure ya'll have conveyed the message to Andrew that the E-Ultimate is on tC's of the same year with revlimiters beyond factory and the ECU is not reflashed. I'm at 6800rpms with the E-Ultimate.

 

think ruswolf has done it on his 2.6 hydra tuned by vinny, i dont know why yours wont go over

 

If you look at that box the MAX button is selected so that is the MAX afr which happened at around 3300, it is not showing the avg

 

Still could use some work on the afr's being smooth. Heres a AEM Ems i just tuned for a customer. (weezyfbaby)



Top is the AEMLOG,s Dyno math Calc weight at 2800 lbs. Seems to be not as inflated as when using real weight.

Middle is boost. Bottom is Afr. its tuned for about 11.6 through boost. The cal table is a little off in the AEM. Still pretty smooth. And ive seen better then this!

 

the bottom afr chart is very compressed compared to the mustang chart that shows the same min and max afr values, and takes up way more vertical space than the bottom chart. therefore, the mustang dyno appears to show more fluctuation even though they both vary about the same. tune looks good to me.

 

the bottom afr chart goes from 3200 rpms to 7200 rpms... the fuel table graph is just as smooth with the proper curve to offset raised fuel pressure.

Timing is a little convervative which you cant see on that log, but i tuned for no knock. Some people tune for under 2 volts. But Saftey > Power IMO

 

im not talking about rpms, im talking about the min 10.0 min to 21.0 max afr value on the y axis of both charts. one takes up the entire screen and one takes up less than a third of it. just not really an apples to apples comparison. my knock retard is also setup on the safe side. at 1 volt it adds 10% fuel and pulls 2 degrees.

 

Yup, you should see what some of the guys do on the aem forum.. Pull timing at 4 volts :O

 

Your talking about that i think.. I see now. Sorry for thread jack

 

Sometimes you get resonant frequency from noisy clattery engines. As RPM increases, raw knock will increase, so long as you don't see major spikes above the trend you're good.

 

Any progress? You know if you send me the map I bet you I can fixy.

 

^^ this.

 

We have most of the bugs worked out but still fighting the damn rev limit thing, I am still trying to get you the datalog so you can have a look see

 

My car is at Vinny's place now, so maybe you should call him again and he can log into my car's Hydra and take a look what's there.

just a thought.

 

dang gl on getting rev limit is it this hard on the ultimate??
