The greddy emanage chronicles
Have you datalogged timing? What year is your project car? Where are you measuring your A/F ratio?
Just for reference, the stock ECU and knock sensor combo pulls out timing all the time, even on stock NA cars. I wonder if the emanage being in line has some effect on that. We get no _additional_ knock indication (i.e. no additional retard) on supercharged cars running them up into the 13:1 plus range at 6-7 psi on 91 octane
Terry, are you running a high boost setup? How's the exhaust temp? Which wideband? We use a MoTeC. Running in the low 10's you should be billowing out black smoke at full throttle. If not, maybe the sensor is off?
The wideband we are using is a UEGO very capable and used on all our cars. The wideband is brand new, in terms of billowing black smoke it will rarely do it unless we get under 10.5
The exhaust temp differs so much because of the diff probes uses, placement ect
Sorry to rant, but I don't want to see people mis-led into believingthat a poorly tuned car is acceptable because it is tubrocharged after

the most rediculous emissions standards....

The e-manage does NOT have the ability to shorten the injection pulse width by itself. It is wired into the injectors via a logic OR, if you will.
This is a REALLY signifcant issue when trying to use larger injectors.
Because you don't have the ability to 'properly' shorten the injector pulse
width.
(In my opinion this makes the e-manage worthless for anything other than
stock inj and NO FI)

ignition timing dialed in. THIS is the casue fo your 'tendency to
Unsure what you are using probably an AEM or some other standalone, we all know that an FMU, VAFC, Emanage to some extent is a bandaid. Any piggy back system is. However a full stanalone has its pitfalls as well that are beyond the scope of this thread. The emanage is a compromise in regards to F/I tuning. Its not as limited as FMU/VAFC setup and its not as capable as a standalone. However for the pricing and ease of install and use its a great thing. I cannot stress in how much I agree with you that a standalone is the superior soluton. But we are looking for other ways. Remember 99% of turbo kits do not include a standalone EMS but rather a piggyback fuel computer or FMU. For those that are concerned with ultimate power and tunabilty then yes the Standalone is the way to go.
wow, Terry you really took your time on that reply. You are very detail oriented. I'm sure you will take care of your customer.
I'm just kidding. If everyone runs on standalone, this forum is going to blow up soon.
Haaaa thats funnyYes the AEM is very capable system and one of the best choices out there. But with little factory support, difficulty of tuning for the average Joe and high price tag it has it faults as well
I would only get a turbo if the kit provided an EMS system with preloaded turbo base maps. IMO, that is the only way to achieve driveability and maximum performance. All other options are band aids. Only problem is initial cost--but it would be cheaper than major engine repair in the long run. Pay peter now, or pay him more later... The price for performance.
So the first turbo kit company that offers AEMS EMS standard with preloaded turbo base maps get's my vote ($$). Base maps would save time and $$. Only fine tuning would be required.

I think there is a company that already offers this.....I may be mistaken
Keep in mind that most people running turbo are not even utilizing any stanalone system and running adequatly...I am unsure why everybody thinks that a standalone is an absolute necissity??
If there is a demand we will make it. But a turbo is already in the 4-6k range and adding another 1500-2000 for a fully tuned EMS(That will have to be fine tuned by the way) makes a turbo out of reach for most people. We make turbo kits for other cars (mazda) and had enough people come forth requesting a full standalone. We are currently 2 weeks away from releasing a microtech stanalone for the mazda. Again if enough people want it we will make it

While on the subject who would be interested in say a stage 3 system that would incorporate a pre tuned AEM EMS and larger injectors with our turbo kits?
Again like I stated if there is a desire for this we may offer this in the future, or would most people like a piggy back system like the emanage?

terry,
I think you are on the right path, you are the only one that I have read that is testing the car for the long haul. I said to myself when someone builds a turbo kit and has tested it on a car, driven daily for 10,000 miles and no probles or all problems worked out.
I will buy it!
Until then, I am staying away. So far you are the only person that is logging data and watching the effects it has on a complex motor(to me).
4K-5K is reasonable for the S2000. Anything more is taking a turbo kit out of reach for the majority of owners.
Terry, I say keep up the work, take your time and build something that is more superior for the long haul and you will get buyers.
Don't try to meet the instant gratification market that currently exists.
I'd hate to say it, but as of right now I am leaning toward Vortech SC, for reliable bolt on power.
