Does the HPS supercharger kit come with a fuel management system as well?

Fast55

Yes. The system uses a piggy back "black box" to maintain the correct A/F ratios at all RPM and loads. They do not modify the factory ECU, nor do they support installs with either upgraded (think Powerchip) or "flashed" (think Renntech or Kleeman) ECU tuning. The flash upgrades are worthless to me, as any dealer who works on the car will connect and "flash" your ECU with the latest factory updates while in for service, whether you ask for them or not. At that point, your $1,500.00 Kleeman or Renntech upgrade is history.

My custom HPS 2nd Gen. system included upgraded injectors & an FMU, lets you fine tune your modified engine.

ProjectC55

Does it control timing as well or just fuel?Or is the timing able to be adjusted?

Fast55

As far as I know, they don't modify the timing or anything else controlled by the ECU, there is no need to. Richard, was there a reason to go to different injectors? Was the car still lean without larger (I'm guessing larger) injectors? Are there other mods on your car that made them necessary? Did that increase power? If so, what were the gains? Any dyno numbers on your car?

Richard Galing

My understanding is the hi-flow injectors are included with their new kit, having discuss this with Bill Kavadeles (who engineered the system), he noted one key element to acheiving power & more power are these units. The FMU was added to my particular system due to aggressive ignition timing tables, despite the reflash by Powerchip. After the new year, I'll have my dealer completely reflash my ME control unit...the FMU will stay, as I'm ready for stage II

My baseline dyno was 247rwhp prior to the blower install, with 0 miles of adaptation my blown E430 registered 355rwhp, thus far I clocked 400 + miles and after 500 miles I plan to stop by Mech Tech for some real dyno time.

When on boost, the acceleration is sooooo wickedly aggressive

Fast55: When are you planning to pick up your car from MT? I'll be down there soon, we should hook up bro!

Fast55

So you're the reason my car wasn't done before X-mas!!! Didn't know there was an injector change, but that would make sense at this power level. My 430 only made 223 RWHP stock? First Gen system made 315 RWHP, so you're 40 HP above that!! That should put my 55 over 400 RWHP with the Gen II!! Holy Shiite, this is going to be stupid fast! It's a long drive, so my car is being delivered on a flat bed (hard to get away from work too). Too bad, I'd like to see yours. Are you going to the AMG GTG if/when it happens? I can't make the Euro GTG on the 15th, I'll be in hangin' in Vegas with some friends.

Richard Galing

My car should have been rollin the streets with the blower before Thanksgiving, but due to pre-production parts and the G55 install before me, there were some delays

No doubt the Gen II should satisfy you thirst for power on your fifty-five I'll be lookin to push my 430 beyond 400rwhp on 19" rubber very soon

Don't think I can make the GTG on the 15th either, hopefully the AMG event will fit the schedule.

Enjoy Vegas!!! I was there on X-mas weekend.

ProjectC55

Mmmm,I asked aout the FMU because I'm dropping a 2000 e55 motor in my c43.I plan on going NA for now.I'll be using the e55 injectors so I was wondering if I could possibly use the HPS FMU for fuel control. The only other solution I have is to reprogram the ME2.0 software in the c43 to be like the ME2.0 software in a 1999 E55. Any E55 after 99 uses ME 2.8.I also have a super afc I'm debating on using but the reprogramming might be better because the timing will also be altered with the fuel flow for the 5.4L inj.Please chime in guys with any thoughts. 1000.00 to do the reprogram..

ProjectC55

355 rwhp.Incredible. I probably should have went that route! But I guess I'll have to do it later on down the road now! Nice #'s by the way.

Richard Galing

Depends on your budget???

The Split Second PSC1 is moderately price and allows a stand-alone style tuning via laptop computer using 3-D maps, while retaining all of your factory sensors. The R4 software package included allows you to create and store settings for fuel control delivery, ignition timing, and a number of other settings, but may require additional programmable modules. This route should be far less than the $1K you were quoted.

On the other end of the spectrum, it's tough to beat the tuning capabilities and flexibility of a stand-alone engine management system. The numerous advantages are you can simply program the car to do exactly what you want given the capabilities of your hardware. AEM and Evosport are in joint effort to service MBs in the near future. Cost can be anywhere between $1800-$2500.

Richard Galing

Those #s will increase with miles as the vehicle adapts to it's newly found soul mate :p

If it's not too late...I say get that C43 blown

Fast55

Coolcar, it will be worth the wait, but your car still is still going to be OMFG fast with a stock 55 motor. I'm not sure your drivetrain would appreciate 500+ HP and 500+ ft/lb anyway! I don't know if you already have the 55 motor, but your stock trans probably won't like that much power. If not, it's probably cheaper to put the blower on the 4.3 and keep everything else?

E55Cent

Hey Rich,
I was wondering what makes your supercharger "custom" and how much boost are you running? By the way the carbon fiber guy hasn't contacted me.
Keep up the great work!
Mario

Richard Galing

Watup Mario,

Long time no hear, how's the tranny? Due to some of the performance mods I have, HPS/Mech Tech added extra hardware...better yet, let's hookup and I'll show you. I spoke with Charlie a few weeks back, I know he was traveling to Taiwan for bizness..don't know if he's back yet. I'm sure to meet him soon, cuz I want to pickup an xtra set, I'll hit you on your celly before I do.

E55Cent

Sounds good to me. Are you going on the cruz in So Cal? Hopefully they can come up with a location and time.

The tranny is doing fine, I get it back on Wednesday. They have had many problems getting the new software to read the tranny. I guess there are different E55 tranny software versions.
Mario

ProjectC55

If the joint effort happens that would be excellent.I have an AME standalone system in my heavily modded 95 Eagle Talon TSI AWD. It put down 412 awhp/341ftlbs of tq. The system that you mentioned (Split sec PSC1),how much does it go for and where do I get it from? Dothey have a web site?





I guess when you add price of motor +kit you're right but don't have 8k+ right now. Did you have issues with your e430 tranny after FI the 430 motor? It's supposed to be the same tranny as the 99 E55 tranny.At least the one in the c43 is.

Fast55

The trans in the E430's are not the same as a 55, I found that out for sure. I don't know what's in a C43, but I doubt you have the 55 trans either, especially in a lighter car. I would imagine Richard is pushing the limits of that tranny with 350+ RWHP. My 430 had no trans issues other than to shift late on occasion, bump the rev limiter, and stumble before shifting into second. Didn't happen every time, so I found a work around. I just lifted off the go pedal slightly as the revs came up to redline. Seems the revs came up so fast the trans and ECU were a little slow to react (might have just been my car, never heard that complaint from anyone else). Other than that, my only other issue with the Gen I system was a loud fuel pump in the FMU. HPS gave me a new one under warranty and the noise was gone. The car actually got better gas mileage (with your foot out of of it of course) down the freeway than it did stock, but the difference was slight.

I started a thread looking for info on Renntech's trans upgrades for W210's, but have had no responses. Mario, maybe something you should be looking in to? Don't know what it is or what it does to "strengthen" the trans, so I have an inquiry into them now. I'll report back with what I'm told.

E55Cent

Hey Brad,
I bet you can't wait till you get your car back. Hopefully my new tranny will be fine and I will not have to get a tranny upgrade. I was going to supercharge it but Adam at HPS is worthless. He does not call back on the work line or his cell phone. I'm not sure what is going on with that copmany. I will most likely get the new EvoSports new E55 W210 headers and call it quites. The car runs 13.4 which isn't bad for a family daily driver four door car.
Mario

ProjectC55

13.4 is prettty damn good!I hope I can do times like that with my c43-c5 w202 conversion. I know those headers have to be crazee $$$$$$.

Richard Galing

Having discussed the AEM unit with Gary @ Evosport, a plug & play tune package would cost $5K, a radical price but indeed the level of tuning has greater potential. The SS PSC1 is reasonably priced at $265.

Your Talon must drive like a "Beast"

ProjectC55

Yes it does run hard,I have alot of blood ,sweat and tears in it since owning it now 6yrs.I want to put it on the track this year and see what times she can do.

$5k for a MB AEM setup sounds insane.They make a setup for the BMW's now and it's about the same price as the Talon setup.


I called up the vendor about using that SS setup on my c43 to c55 NA converson and he said that it would only serve my purpose if I was going FI with the 5.4L motor because of the timing retard that would be needed.They also said that HPS is one of there customers and that this is the piggyback system that they are using with their kit.

Richard Galing

On the Gen. 1 bolt on system.

ProjectC55

Does Kleeman use piggy back or do they change the whole ECU?And what does HPS use to control the fuel and timing with the new kit now?

Richard Galing

On the Kleemann kit, I believe the extra fuel demand is handled by a Kleemann fuel pressure regulator, however they do offer an ECM upgrade.

The HPS runs stock software in conjuction with the hi flow injectors, my particular setup adds a fuel regulator assembly for added boost.
