Digital 930 CIS controller F/S

[lite75]

Greddy Digital CIS Controller for 930, uses ECU to control frequency valve that varies fuel head control pressure. Comes with Greddy Rebic IV digital controller, ECU, MAP sensor, frequency valve with all connections, wiring, wiring diagram, programming manual, base fuel map, custom console with A/F gauge and oxygen sensor. System does not need a laptop to program, fuel map is created using buttons on the controller based on MAP, RPM and frequency valve settings. Controller has digital readouts for MAP, RPM and frequency valve duty cycle, also with peak and hold functions. System doe not have a cold start map, thus the WUR is retained with the MAP signal unhooked for cold starts only. System has been used on my car for 18 months and works excellent, like new condition.

Selling because new motor is using 3.2 intake with EFI.

PM for more pics.

$600.

So this unit automatically controls fuel pressure and keeps your air fuel ratio in the green, so wouldn't lean out and damage the motor, am I correct. Looks like a very clean installation, how diffacult is it to hook up?

what model/part # is that from greddy?
Would like to see some more info.. interesting

Greg 930- Yes, it replaces the enrichment function of the WUR under boost so you can fine tune the A/F ratio just as you do with efi. The installation will take around 3 to 4 hours and includes all the components for operation.

onboost-Its a GReddy Rebic IV unit

Thanks, Dan

Reduced to 475.

i will purchase!..pm sent..please read.thanks

Wide or narrow band 02 sensor?

I guess the question is how quickly it adjusts the fuel pressure and how much better EFI might be?

[laughac]

I think I might want it when I understand it better.

Hahaha...

First job is to get the stock 930 engine installed and running in my '77 slab side 911s. After that I'm sure I will quickly develop a new set of priorities.

Hello Stup

You want to make a collection ???

[Blaine Sellie]

Has this item been sold? I'm local......

[slow&rusty]

Please represent your "wares" correctly and know what you are selling. Greddy never made a CIS Controller further more the Rebic is ONLY an injector controller and does not have an ECU, MAP etc...unless you are running a standalone and you have removed your CIS...your post is a mish-mash of confusing.

Yes, it is a injector controller that I use to control a frequency valve (same as a efi fuel injector) to bleed down the control pressure and this IS done using a map sensor. No, Greddy did not sell this specifically for a CIS controller but it works excellent for regulating control pressure under boost.

Thanks for your interest.

Hi can you post details of how this setup works, a diagram or photos would be good if possible.

This thread starts with stup tuning injector flow (which should be required reading for folks running CIS anyway, IMHO):

Meter head flow adjustment question?? It seques into him tuning the exact Greddy/frequency valve combination that lite75 is selling here, and details his (excellent) results with it.


In this thread, Thierry is doing precisely the same exercise, except using a Split Second AIC instead of the Greddy:
