Yeah you guys are right when you are telling me to wait to bring it to protomotive. I may just do that. I don't have any schematics of AEM, it was never tuned just installed. I want it done right and waiting is the only way. Has a rear main seal leak I think and that needs to be done asap. Ill just drop the motor and do anything that needs to be done to make it perfect.

 

A decision that you won't regret. Promise.

 

cool cars of the 90s, It stinks I can't drive the 993 I want to so bad!

 

^ nice!

 

If Rich Jacksic did the machine work - it is perfect. The fact that it is motec and and not Porsche Motronic, tuning it shouldn't be all that difficult. I would reach out to Geoffrey Ring (gring@racetek-engineering.com , RL'er) who is an expert on tuning with Motronic and can at least steer you in the right direction. Also, Joel Reiser (out of Rochester, PCA tech for 993's, has a GT2 with Motronic he's been developing for years also knows these things inside and out and might offer some help). Don't get discouraged too quickly. PO spent tons on this thing and built it with all the right bits. Tuned properly it should be a rocket ship.

 

Anyone notice the number of EFI setups in the build sheets...first Electromotive, then Haltech, then Motec and finally AEM...wow

 

Thats the first thing I noticed too. Why so many ecu's? I hoping AEM with the VE tuning will be the one that works! I have a guy from AEM coming to the house hopefully this week to plug in the computer and see how the AEM infinity is set up. Next week I will have the RMS fixed and drop the motor to see if it needs any other seals. Thanks guys for all the info and help.

 

this is typically why modified cars sell for less....
Sounds like if you get this thing running right it will be monster!

 

Any advice on going ahead and tuning for E85? I think that would be best for the car but not sure about bad effects from e85? I have high flow injectors but maybe the pump will need upgrading to complete e85 tune?

 

availability of E85 local to you. in Cali it's not practical as I don't even know where to get it. For Forced induction cars I've heard terrific things about E85 since it's octane rating is so high. I want to say Rennlister TACKER in Texas may be running E85 or had some experience with it. I may be pulling that out of my *** and so apologize if I am wrong.

Remind us again what pump(s) are on your car. any good tuner that knows how to tune with E85 should be able to guide you with how much flow is needed for the HP levels of that beast.

 

Not sure on the fuel pump, I think stock still? But E85 is available everywhere in MN so I was thinking why not. The tuner said you can get like 70 more HP with it.

 

I think you should first try to get it running properly and diagnose any issues before switching fuel and what not. Just my .02

E85 is a great fuel and someday will covnert.

 

Quote of the day considering all the other issues the OP has highlighted over the last few weeks. Fix it first then worry about the rest.

 

So the cars been up at the tuners for months now and they do not know what they are doing. The wiring was all checked, new map sensor, pressure tested to 15 psi no leaks. The AEM infinity ecu they say needs to have a cam position sensor to be able to run and tune the engine. There are no cam sensors on these 911s and is seem the crank sensor is giving the ecu both cam and crank positions but I don't know how and they certainly don't either. Does anyone have knowledge on how to get the ecu to read cam position? Are there crank wheels that are needed for this application that are special? Any help would be awesome!

 

Did you have anyone with AEM come check out the system? I would have to think that a CPS could be enabled or disabled within the tune. A system like AEM Infinity has to be able to accommodate many different engines and most older engines were never equipped with CPS. You don't REALLY need CPS for basic VE tuning. Doesn't make sense. You either need an expert in using AEM Infinity system to check out the tune or ditch the whole dang thing. Sounds like this machine has chewed up and spit out most stand alone ECU's so this option might not be realistic. Good luck!
