The hold up for me Shark tuning has been lack of proximity to a Shark Tuner owner.

This seems the most cost effective route for me with the features I need to tune this car for the street (as it will never see track). I may go with a Sharktuner afterall..

Rick,

I can make you a SharkTuner Owner and fix that "lack of proximity" issue :-)

I'd say that the biggest reason would be cost.

I've had one of the piggy-back type computers, that's like the SMT-6, in my car for nine years now. It does what it's intended to, which is to allow tuning the air/fuel ratio and ignition timing. I've used a SharkTuner on other people's cars, and it does work very well. Ideally I'd definitely prefer to have a SharkTuner and a set of PEMs rather than the piggy-back computer, but the piggy-back computer does what I need it to. Right now, a SharkTuner that has the option for the '85-'86 cars and a set of the PEM modules costs right around $2,700. One of the piggy-back computers can be bought new for less than $400, and loading different maps into it can be done as quickly and easily as loading new maps into the SharkTuner PEM modules.

I like the ability of the stock EZK to monitor and control individual cylinder knock and ignition timing, and that would be a strong reason for me to want to stick with the EZK/LH system with some way to tune it. Almost nobody here will ever have a 928 that would ever really need anything more than an EZK/LH with a SharkTuner is capable of doing. With an '87 or later car, I'd say the best case situation would be to buy a set of the PEM modules for $200, and find a friend with a SharkTuner that will let you use it any time you want.

If I had a pre-'87, car that doesn't have the EZK system, I'd go with a Megasquirt or an OEM ECU from some other type of car to control both fueling and ignition. Both of those are options that people have sucessfully used on 928s, and that can be done for significantly less cost than either the vast majority of aftermarket ECUs, or the SharkTuner with the stock ECU.

Rick,
Proximity is a relative property. How's your shop sound for proximity? Soon they will be more affordable. Just figure it in with the cost of your SC or other performance mod.

In 4 days that will no longer be an excuse for the 87-95 models. :-)

Whaaaaa? Do tell!

I use SMT6 on my supercharger 84 EuroS (GT2s) since two years now. This is working great, just clocked 800 track miles last week end at RA.

DR

Can't give out details until SITM..

Rick Carter

I understand costs of R&D. How soon will it not be an excuse for 85/86? SITM is not in the cards for me this year but I'll see both of you in Dallas!

Mongo

mmk but I won't be at SITM, so I guess I have to wait as to why it's going to be less expensive

Andy,

I've been using the Sharktuner and PEMs on my car for many months. It's been a great tool
for tuning the engine. I'd recommend it wholeheartedly. And with the Mark II it should
be even easier (and cheaper).

The perfect power smt6 & the like are useless, as you do not have access to the trim maps in the the twin bosch ecus, you can add fuel via the analog maps & modify the ignition, but its a big but .
You cannot controll the trim maps when the throttle is at wide open throttle so what ever you do is a complication , if you are a tuner, as I am ,you only have to watch the Lambda values until the wot is engaged . the mapping will stay at lambda 1 or thereabouts until the switch is engaged it will then add or subtract the values from the trim maps .
The whole idea with the interceptor package or ecu package is to optimise the fueling across all the cells to obtain maximum torque under all mapped conditions , this cannot be done for the above reasons . The only way you can access all of these is with the sharktuner, with this you can turn off all the wot trim maps & map via the base maps, if you need to add more fuel or ignition or less you can than adjust the trim maps from there .
Of course you have can also throw the whole lot away & replace the ecus & wiring .
