Trying to install my guru chips today... and I can't find the region coding plug. There was supposed to be an image attached to the email, but it never arrived.

The description of 5cm away is a little too vague for mechanics of my skill.

Thanks in advance,

Justin

 

It is a two hole receptacle(female) about 5 inches(12.7cm) away from the DME plug harness. It can either be sticking just out from the harness wiring or have its own wrap for an inch or two.

 

Whew... good thing I didn't start pullling jumper plugs on the DME board. I thought it meant 5cm away from the DME chip. Does anyone have a picture of what I'm looking for?

 

Justin, here's a picture:

You can wire up this plug with a toggle-switch to flip between the street and race-gas ignition maps. Follow the instructions sent with your Chip Upgrade Kit and make sure you only use the advanced ignition settings with race-gas only!

 

My plug does not have the jumper attached. Which was is for street gas?

 

I is a kolledge gradiut.

Are there multiple types of jumpers for this plug?

 

No jumper for street settings

 

This is what I have from the instructions Danno sent me for my Stage I kit:

"There is a two-wire connector about 5" away from the DME connector. Make sure there's a plug with a shorted wire loop there. If not, install the jumper supplied with your kit. This selects the ignition setting for street-gas and ignition. Otherwise you'll get a 4-degrees ADVANCED ignition map which is for race-gas only."

According to that you SHOULD have a jumper in there for street settings. The jumper that's included is a little piece of wire with a metal plug on each end. Stick both ends of that little wire (the jumper) into the plug and you're done. If you look at the pic Danno posted, you see a short red wire looped into a black plug that sticks out from the other wires - that's the plug that needs to be jumpered. On my car it was already jumpered.

I don't think there are different kinds of jumpers - I think it's an on/off type deal.

 

Cool, thanks Danno. I guess that must be the picture that got misdirected from the email. I've left my superchips in until I was sure that I knew what I was doing. I guess I'll see tonight how much the guru DME chip alone makes to the performance. The beast is already stupid fast with the everything other than the chip installed.

Thanks again guys!

Justin

 

I don't remember seeing anything about this in the instructions I received a couple months ago. Is this only applicable to the Stage I kit or does it apply to the basic chip upgrade kit as well?

I have been running my car at momentary WOT to see where the boost peaks on the VDO meter and have dialed back the Reliaboost but I still see 20 PSI - admittedly slower to climb up there but nevertheless will still creep up past the 15 PSI threshold.

I am wondering now if the timing advance has any bearing on the boost levels produced.

A more fundamental question though - does the jumper come as a stock item and (in my case) was it inadvertently removed by the PO in the past?

-----and does the Guru chips alone require that it be present???????

Thanks

 

On the '86-87 cars, they typically come with the plug installed. However, the plug is not used to make fuel or ignition map changes, so it doesn't matter if you have it on or off (the settings will be the same). Only the FQS switched in used for this function on the 24-pin DMEs.

The '88-91 cars with 28-pin DMEs comes both with and without this plug (depending upon the region of the world your car was designed for). You want the plug OFF to select the street-gas setting. Then the plug should be ON to select the race-gas settings.

"I have been running my car at momentary WOT to see where the boost peaks on the VDO meter and have dialed back the Reliaboost but I still see 20 PSI - admittedly slower to climb up there but nevertheless will still creep up past the 15 PSI threshold."

Mechanical boost-controllers will always give you lower boost in the 1st three gears on a stock turbo. Make sure you adjust the boost-controller to give only 15psi in 4th and 5th gears. This will most likely result in 12-13-14psi in 1st-2nd-3rd gears.

Does "off: translate to no jumper and "on" to jumper installed?

 

That's the way I read it.

According to the above quote you SHOULD have a jumper in there for street settings.

I hope Danno clarifies this because I am really confused as to what constitutes stock and 4 degree advanced timing.
