I'm new here so please be gentle. I have read the rats nest removal section. However, that describes the removal from a carb. car. Is there a separate thread or section on removal from the 1984 EFI 13b motor? Or should I just leave it alone.

Any help or suggestions will be greatly appreciated. Thanks.

Drive well.

 

The rats nest on the -SE's is a lot trickier than on the 12A cars, due to the fact that a lot of it is used to contol the FI system...

I've never seen any write-up on what can be removed, but I'd be VERY interested if there is one...

 

I have always wondered the same thing and would be awesome if someone did a write up on this. *Hint Hint*

 

How about a write up for the removal and also the preservation of the EFI. Seems like everyone just yanks the EFI off these.

 

From what i've read, You cannot remove much from it...I believe it was like 1 solenoid...Not sure what...But it wasnt worth the work so i never bothered. That was alot time ago though, havent seen it ever again.

 

The easiest way to junk the rats nest is to get a replacement EFI.

I'm looking at doing a MegaSquirt setup. Cheap but good...

Wasn't V8klr working on a MegaSquirt?

 

I also don't think that there is much that you can remove on the SE rats nest. You could get rid of the relief and switching solenoid on the firewall if you had no ACV and aftermarket exhaust or gutted cats. The fuel pressure regulator solenoid (orange connector) may be able to be removed, but it is part of the hot start assist. The green connector is for the vacuum advance. The two other solenids (vent and vacuum) are for the BAC valve. I have heard of people removing the BAC valve and related soenoids and vac lines, but I don't think that I would mess with it. You would probably have to bump up your idle speed so that when additional load was placed on the engine, it wouldn't stall.

Yeah, V8klr was doing a MegaSquirt setup. I am actually going to put one in my SE as well. I have it built, sesors setup, and the engine will run on the MegaSquirt. I just havn't had the chance to do any tuning yet (so many other little things to fix on the car). It has a lot of nice features in addition to be fully tunible.

First, you can ditch that restrictive AFM

The ecu has a flood clear mode (just hold down pedal while cranking) No more pulling fuses, using fuel pump switch etc.

There are a few people that have put one on the SE and don't use the BAC valve. I am going to first try it with the BAC valve and see how it is

Anyway, it is a pretty cool setup. I will keep you all posted once I get some tuning done.

is there a megasquirt / Gslse thread? I wonder what intake would work well with the gsl-se and megasquirt..

 

Ditch the AFM in place of what?

 

The megasquirt is MAP (manifold air pressure) based. It uses an 8x8 table of manifold presuure (which is related to load) and rpm. This is similar to Haltech and other systems. The megasquirt is much cheaper, ~$130 compared to about $1000 for other systems. The megasquirt only does fuel in its present form while Haltech and others will also do spark. There are other megasquirt spin-offs that do spark if you have high impedance injectors (the SE injectors are low impedance) for boinger applications. No one has made a megasquirt for rotaries yet, but Bill Shurvinton on this site is working on one (rotary spark).

You can find out more about MS at:

http://www.bgsoflex.com/megasquirt.html

There is also a Yahoo! group for it and the people are quite helpful. I would recommend reading through the MegaManual to get for info on what the MS does and what it doesn't.

For the manifold, you can use the stock SE manifold, 2nd gen manifold, or whatever if it is a 13B that you are converting. For a 12A it is a bit more work. My setup is pretty simple, I am using the stock coolant and air temp sensors, injectors, manifold, etc. I added some connectors into the stock harness. This way I can easily switch between stock ecu and the MS.

Good stuff dude. I know it's a lot of work, but more and more GSL-SE owners (including myself) are looking for ways to ditch the stock, crappy RE-EGI system without going to a fuel hungry weber or holley. If you could document any of it, that would be great!

Personally, I'm doing a swap to FC injection/direct fire ignition in the coming month. It should eliminate a lot of the rough running characteristics I've been experiencing and (hopefully, and what I'm told) make quite a bit more power. I'll be running an 86 manifold and DEI chamber and I'm going to have the wiring harness spliced to accept the 2nd gen ECU. With the new injection comes 2 more injectors, for a total of 4. I'll be running 450cc's as primaries, and GSL-SE 680ccs as secondaries, for when you really wanna romp on it. Hopefully this will put the car well into 14-second range. I know a lot of this has been discussed before, but there's no such thing as too much information when it comes to this subject, IMHO. Pictures, documentation and most importantly, impressions, will follow the install. Wish me luck!

i removed the rats nest... runs great! enough said!

 

Im ditching the EGI completely and going to ITB same as dj55. Parts are one the way as we speek.

 

Here is a GSL-SE presilencer.

 

what site r u getting ur itb's from? im thinking of doing this set up too

 

On the contrary, the 12A carbed cars have about three times the amount of rats nest crap compared to the GSL-SE.

My SE has a full S5 intake manifold still utilizing the SE AFM, twin injectors and ECU with the rats nest removed and all necessary vacuum lines rerouted. Runs superbly

 

It would be a great idea to post pics so others can get an idea of what can be removed and what needs to stay on. I too am in a similar situation with an s5 n/a motor I will be building to handle a 100-150 shot of spray. Want to keep it simple. No rats nest on an Fb is easy.....not as simple on a FI motor.

 

fuji-racing.com but im pretty much stealing dj55 setup(hope u dont mind) so look at his threads they help alot
