I wish you the best of luck with this.
But in my opinion, you put the cart ahead of the horse. You should have gotten a standalone system or one that you could tune with a laptop, ie pull timing. adjust AFR etc. BEFORE going the SC route.
But I am just **** about that sorta thing.

Oh a standalone would be the best for sure! But there are tons of setups out there running these boost levels and using the stock system.
Was researching some info on the NGK site and they say for each step colder plugs it lowers the combustion chamber temps by 75 - 100 deg C. Will be interesting to see if this helps or not.

Will the Sharktuner work with an EZF to manipulate spark? I noticed the add on says it is for the EZK.
I ordered some Bosch WR5DC plugs on the way to work and they will be in this afternoon, just plain copper cores 2 steps colder then stock. I will see how they work, but we have snow in the forecast for the next few days so no test drives .
Silly question, I am running 91 octane right now, select stations here offer 93 - 94 should I be running the 94 all the time now? The stations with 94 are an ethanol blend.

There is a version of Sharktuner Mk1 for LH2.2 and EZ-F for the early 32v like yours. This is what Tim and others use.
Your cooler plugs may run cooler, but that won't affect the temperatures in your cylinder, which depend on intake airtemp, compression ratio, boost, fuel octane and A/F ratio. Once you go over a certain temp in the combustion chamber then you get detonation.

I did the inital setup / tuning on Shane's 86.5, and I can report it works great! It worked so well I'm converting my 81 to LH/EZF so I can finally SharkTune my car.
How much ethenol? I would not run more than 10% with stock fuel hoses and injectors. Otherwise go with the highest octane you can find.

That would be perfect, I gotta get some guys together here in Ontario to do a "group buy" on a Sharktuner LOL!
I think it is only 10% ethanol so it should be OK.
I have so many different ideas on what to do, but am trying to decide which way as the all cost $$. I think the wideband will definitely be a good idea so I can stop running blind. My 24 lb injectors using the stock chips are probably maxed out, I believe it comes to a point where it doesn't matter how much more fuel pressure you add the injectors just can't physically flow any more fuel until you adjust the injector timing so they stay open longer. These injectors are the originals that came with the car and the PO says he had them cleaned a few years ago but who knows??
The original FAST setup had 30 lb injectors running stock fuel pressure with the option to run an FMU. Will the LH be able to correct the AFR using a stock chip in closed loop while on cruise when the car is not boosting or will it over fuel? I had a couple leakers on the 30 lb Accel injectors that came with my kit so I sold them cheap on Fleabay. My local Steeda dealer can get me 30 lb Ford red tops for a good price and if the LH can adapt to them that should take the fuel enrichment out of the equation.

As John pointed out, the SharkTuner does work with EZK.

You can SharkTune for 30# injectors. You just reset the fuel injector size options shown on the Parameters screen..... then the base map is automatically rescalled for the larger injectors. So the map is close before you start to optimise.

Without Sharktuning how would the stock LH do correcting with the just the O2 input?
#56
Rennlist Member
Not sure I understand your question...... when you talk about "O2 input" do you mean the NB O2 to the LH, or a WB signal (which is used with a gauge or the SharkTuner ?
You "probably" can get away with your 24# injectors and still stay within the limits of the O2 loop in the LH.

Hi John
I was wondering if the LH would be able compensate for the 30 lb injectors by using the input from the O2 sensor in closed loop without Sharktuning. My stock ones are 24's.

OK, understood. The O2 loop has a range of about +/-22%. 30# are a 25% increase in flow compaired to the stock 24#, so even they seem doubtful.
You could drop the idle fuel pressure, but that leads to other problems. Not recommended.

I thought the 85/86 cars came with 24# injectors.
