AEM Update

[O-Gauge Steamer]

So, I have had a couple of PMs asking how the AEM is operating...

To date I have had Zero CEL events, my AFRs run in the mid 14s except under full boost/throttle accerations where I run it fat in the low 13s. I have Zero detonation.

I propose that we share the maps developed to help out those just starting down the path. No two of the maps will be the same, but it would give a head start to the members attempting this task.

If anyone would like a copy of my F/IC8 map, drop a line and I'll email it. Keep in mind that my frequency map is set for 4.56:1 gears and P285/75R16 tires. It would make a good start though, just correct the table for your combination. I took a stab at doing the math and was close, final adjustment was done on the hiway as tires are not always the size the manufacturer claims they are...

Be advised that F/IC6 and F/IC8 maps are not compatable.

So do they have anything for OBD1 guys who are wanting to go to forced induction?

 

[O-Gauge Steamer]

I have installed a Sprintex Supercharger on a 93 YJ using the F/IC6. The AEM unit does not care what factory electronics are on board...

Sprintex will tell you it can not be done.

Wrong...

I see no reason why the FIC or any other piggy back commonly used on Jeeps won't work.

Given the way the AEM works, it really does not matter what you wire it into. The injector drive is interrupted, modified by the AEM and then is sent off to fire the injector. Easy-peasy. They are a dual processor (Fuel/Ignition) box so signal latency is not an issue.

The 93 I did had essentially smaller injectors (39psig fuel pressure) so I just rescaled all of my values and used that as the starting point for the tune. We actually only made a few minor changes from there. It was completely drivable at the start. Biggest problem I ran into was that the YJ had a vacuum leak and that had to be found and killed.

I can endorse the AEM as I am more than happy with the performance.

Perfect Power units, on the other hand, I suggest you stay as far away from as you can. It completely mangles the ignition and too many parameters are locked into firmware, not accessible to the tuner. I would have stayed with the 7th injector idea if the AEM would have driven it with each of the stock injectors. In the "extra" injector mode, AEM fires it in conjuction with the number 1 injector only. I could have done it by adding more electronics, but after extensive dialog with AEM, I decided the best solution was 6 larger injectors and to abandon the 7th. Much easier.

Wait. What?
Aren't you the same guy that made my life a living hell when I suggested the very same thing? Wow.

 

[O-Gauge Steamer]

Actually, Mr.Yan,

I suggested that you do something instead of just whining about how bad you have it. How poorly you have been treated. How abused you are.

To be blunt, I never told you to run a seventh injector as the hardware you have does not support it. The unit you have, when new, dealt (sort of) with the fuel issue by using a rising rate fuel pressure regulator and did absolutely nothing about the ignition.

And, for that matter, have you done anything? Or, are you still waiting on Rimmer to bail you out? I can tell you with certainty (even though I have completely severed ties with him) that it is never going to happen.

You want your used supercharger installed and running? Get off your duff and do it.

I invested nearly $1,000 to get the Sprintex installation to work as it should. New injectors, the F/IC8 a UEGO Wideband and a cheap laptop so it could be tuned. Not caring for either the performance or the support I was getting, I did the research and purchased the components. Did the installation and had it tuned in a weekend. And, now I am looking to replace the compressor with a Whipple as 5lbs of boost just is not enough.

You, on the other hand, are what? Two+ years of complaining?

So, go ahead, trash this thread instead of contributing something positive.

If changing the story makes you sleep better at night than so be it. I know what happened, and I know you're a grade-A turd.

BTW, you needn't worry about me complaining or begging for your precious help anymore either. 505 Performance is helping me out; in fact, I would-have my SC running a long time ago -via 505 - if I wasn't sidetracked by you and Rick. They didn't feed me any long-winded BS tales how I should buy a new SC because mine's a POS, or how it couldn't be tuned cost effectively. They offered me a tuning package - minus the drama - and it's awaiting install as soon as the weather clears up.

So thanks for nothing; the lies and insults have-been a blast,

 

[shawnxj]

hope you have better luck with the 505 tards then the people who payed $4k for the turbo kits that can't be made to work with the parts they included in their kits......you might want to research the people you do business with better

 

[urban yan]

No one’s service could be any worst than what Rick Rimmer and o-g-s put me through this past while. Allot of the F/I guys on naxja like to talk big and brag about their set-ups.. just don’t ask them for help -- that’s when the drama starts.

505 uses a Flash Programmer made by SCT/ tuned by Performance Injection Equipment out of Georgetown Delaware; all the fine-tuning will be done by those guys... just send them your A/F figures and they’ll email you a new tune for the SCT. The price-point for the tuner/larger injectors/ 2bar map was reasonable too.

While I don't know the details between you and Rick, I can vouch for many when I say that you simply make it hard on yourself. There are many people that not only can vouch for the AEM, but are truely willing to help others tackle the endevor...

Me, Gradon, Tayln, O-Gauge...just to name a few have had great success. Other than take on the project yourself, you'd rather complain about it on the interweb.

Do something for yourself for once instead of hijacking other threads.

The 1913 Unit would work great for you. :thumbup:

Feel free to PM me if you have any specific questions.

Hah, you're one to talk. I know of two people who PM'd you for help tuning their AEM; first you said yes than you bailed.... and let's not get into your disappearing JF RMT thread.

oh and BTW, the only thing I've done to make things hard on myself is to trust people.

 

[Talyn]

I can vouch for Urban's bad experience with Rick. I've been following him from the start, way before O-gauge got on board, and Rick is nothing but hot air and lies. And I wouldn't doubt that Rick told O-gauge the same lies that made him smell like roses. I've said this before, I can see why Rick has been through so many different businesses, different iterations of his supercharger, and a long line of pissed off customers.

Who? I've responded to everyone that is nice enough to send me a PM. I may not respond immediately like a crack head computer junky, but I will respond. Hell I'd still even help your sorry ass if you asked nicely.

I'm not a vendor on JF, hence the disapearance. Simple as that. :banghead:

 

[urban yan]

Great answer. You should run for politics.

That sucks and is clearly no way to run a business. I'll admit that, but...

That has nothing to do with AEM or the point of this thread. O-gauge's intensions are good and just like the other genuinely kind hearted people of , loves to help others. O-gauge is not Rick nor had anything to do with the operation of his company. Thus to throw him into the fire is simply childish.

 

[urban yan]

You're right, O-gauge certainly isn’t Rick, but he certainly acted like Rick’s gatekeeper and PR department for a while. When I PM'd o-guage -- asking politely -- if he "could ask Rick to drop me a line" (when Rick went M.I.A.), he gave me this "genuinely kind hearted" reply:

I would suggest that having the appearance of "badgering" Rick will not endear you to him. Also, if any of this communication winds up for the general population of to read, I can almost guarantee a "no-response" from Rick.

oh yeah, he also told me it was my "bag to drag with Rick." He also slandered my suggestions that any (XJ) supercharger would be better served via an AEM box/ 6 injectors only to start this thread/ act like the past never happened. Yeah, he’s genuinely kind hearted indeed.

 

[O-Gauge Steamer]

Do you actually read what you post?

Yup. In fact:
Your posting of the badgering has not endeared you to anyone.
You are getting a no response from Mr. Rimmer.
And it is your problem, not mine.

Post the slander. I am glad you feel it needful to keep every email you get so you can throw it up at a later point. I deleted yours pretty much as fast as they came in. Good to know I have free rent.

The seventh injector works for fuel delivery but the SMT8-L Perfect Power piggyback is incapable of correctly dealing with the ignitionon the Jeep. The reason for this is that the Camshaft Position Sensor and the Crankshaft position sensors are separated instead of being kept together as is done by the AEM F/IC. As a result, under a very specific condition (under boost just prior to the AW4 downshift) the ignition gets "confused" and the PCM actually shuts it off resulting in what can be called a lurch. I was forced to drive in town with the transmission in 3rd to prevent the fault. Sprintex is re-engineering the box to correct the issue. but I could not wait for it.

I have refrained from saying why I moved away from Mr. Rimmer. Suffice it to say that he lives up to his reputation and I do not care to have the mud thrown on me as well. That he deserves the mud becomes obvious to anyone who has to deal with him.

I believe in giving everyone a blank page to wrire their relationship with me. Mr. Rimmer soured his and you soured yours.

As for you, you continue to reaffirm my faith in humanity. Some folks are best at shifting the blame for their short comings onto others. You and Mr. Rimmer should be best pals based upon this particular quirk.

How many years have you been looking at the SC?

Hopefully, this thread can get back to the intended purpose. I still feel that there is a benefit to be had in the pooling of the knowledge of those of us that have been successful in the pursuit of Forced Induction. My FI experience starts back in 1963 when my Dad and I built a blown 52 Ford F1 pickup with the Flathead V-8. It was my first engine rebuild. Where were you in '63?

I again extend the offer of a functioning F/IC8 map.

On the other hand, if it is just going to be a platform for the rantings of a dissatisfied individual, then I ask the Moderators to close it. Anyone wishing to have dialog can just PM me. Be advised that I will not respond to this thread again if Mr. Yan continues as it is a phenomenal waste of my time.

 

[bigdaddyjlove]

In the spirit of the original thread, did you use the AEM jeep/dodge specific plug? Or is it really out of production?
