Not a plug and play. It will be totally independent. This is going to be a lot of work. All the stand alone's I know of on our cars just do timing and fuel. I have removed the vario and some other odds and ends so the factory ecu is going to be mad. There is software But its up to you or who ever you want to tune it. I will update as I do..

 

Tim , why you switch to standalone ?? i saw many 1300hp porsche projects that use oem ECU , what i remmber is when EVOMS ran their EVO1500 997TT they was useing stock ECU , but they faced the traction controll issues !!! so is it worth all of that work going to standalone ??

plus , why you did not switch to proefi , they have plug and play standalone kit for porsches !

best as allways

 

I dont believe half of what I hear and even less of what I see when it come to what has been done to these cars. The 997 is a whole different beast and better in my eyes for upgrades. proefi is a piggyback. I removed some systems from the motor that the factory ecu can not work with out so no factory ecu need a stand alone. MoTec is top shelf.

 

Don't say that!!

Now we are going to have the market flooded with 996 sales!
But look at Joe's car, Powell's. Fastest Porsche's out there are still 996's got to say something there

 

LOL I know. After all I spent on my car its not going anywhere. The only way I will part with it is if (when) I crash it.

 

Agreed 100%

Also where are all those ProEFI cars? I think Switzer is the only one who gives them a chance time and time again but after talking to several major tuners (not Porsche, but people who tune for Outlaw radial cars, etc.) they know who they are and it seems the product has and will always be a giant let down.

In the end my system is not a piggy back, but it is (if that makes sense). A true piggyback in a sense works different. Off the DME I have a lot of wires that go into MOLEX connectors that don't have other ends. I still rely on the stock DME for a commanded idle and a higher than stock rev (factory limiter is 16k on my car and 8300 on my fcon). Then becomes another issue with HKS is that you have to have a pretty little USB key to even tune it.

Had I known what I do now where I was going with the car. I would have a Motec and a racepac or aimsport dash... So much easier!

 

Does the stock ecu control the cams still? How about the drive by wire?

 

Great shots of the build. Thanks.

 

Cam control was an option because the one plus with the Fcon was we are able to output signals (and this is key as to why the whole idea of a standalone was unheard of for a long time). On the first iteration of the install (Justin's 996TT) he made that part of everything happy (ABS/PSM/etc). That being said we talked about cam control after the motor was built. Long story short the cam issue I thought would be fixed by replacing some things didn't fix it. So the car still had a switch over issue at cruising speeds at 2400-3000 RPM on the passenger bank. I ended up just grounding out the actuator so the cams are locked in high cam, and then grounding out the DME side after a few weeks back in Houston. I always said we would re-address that issue but it's never had any other issues so it's still sitting in the back LOL.

As far as the drive by wire the Fcon on v3.3 (current version and what I run) you could not control the actual drive by wire system.

In a sense yes it "piggy backs" but as far as the definition of what a piggyback system does on every other car it is not what we do. Then again I think the Lambos do the same with the AEM and I also think the Motec as well. We are not emulating or breaking apart any information like that. That is also why I have an igniter (and DLI now), injector driver boxes, etc. to make it oh so fun and compact back there with all the extra wire LOL!

Like I said if I could do it all over I'd do a Motec any day and say screw the factory dash. At the same time that would allow me to run another intake setup and like a single 90mm-102mm TB and all that other fun stuff.

 

Thanks for looking.

 

When will it be ready so I can get a ride?

 

I have been thinking about this for over a year now. I Did not see where the vario would honestly help me for my cause. Also the lifter I am using is 1/3 the weight of the intake lifter and 1/2 the weight of the exhaust lifter. I am running a cable TB now. I want to do drive by wire so I can use the traction control in the moTec. I bought the options so they are there in the box.

 

Guess I am not the only one burning the midnight oil... Soon..

 

Yeah I originally planned on getting rid of it entirely, but there were a lot of different things going on during my motor build that sometimes I wouldn't communicate things (dad dieing at the beginning of the build and then both Matt and I moving close to mom a few months later really wasn't helpful). Although I think all my hiccups here and there are some how him funneling his hatred of that car down because he wasn't suppose to know about the built motor till the day he got back from vacation with our mom... Hopefully Matt's 280Z takes his hatred now and mine will be safe!

I know we used different lifters but I cannot remember the differences. That was the intent was to not have variocam. Dave at Headgames had talked to Meckenzie/Proto and a few others about that. I had hopes to rev the motor to 9000 RPM, but Justin was very much against that even though at 8300 we still are making power. The way I was explained (and I'm trying to remember what exactly was said a year ago) is because of the large bore, small stroke and it being a flat motor basically the piston is like a mace so you add LOTS AND LOTS of cylinder pressure and LOTS of RPM then issues can arrise.

We actually tested it on the dyno since it was just simple as grounding the wires out. If you don't ground the DME out the car some how has a 6800 RPM rev limiter again FYI for anyone who wants to disable variocam. There was like ~200 RPM of spool lost, but that could have been probably changed in the tune. So honestly the headache of trying to make it work again and then tuning the output to them wasn't worth it.

 

If it were not miserable down here in Houston I'd be doing the same to get a lot of projects I want to get done on the car. I've got a list of tools that I know the neighbors have legit reasons to call the police for noise complaints for so at night my tool selection is not always as open LOL!

Why can't I have you as a neighbor so at least if I hear the pit bike I know to bring out the golf cart because a race will be going down soon after! LOL!
