No I am saying there is no decent intake for the computer engine style for the V-6.There is a good one for a carb.Nice aluminum high HP style.Dyno program showing a big improvement with it alone. I good with 60 thou volts timed correctly.Since I got a OBD1 I kinda burnt on the tuning aspect.Buy a 200 dollar special chip if it not what you want your burnt.Or buy a chip burner again not cheap. Or go with something cheaper that easily tuned.I still shopping to see what out there.I will never rewire the van like I seen done.Hot, ground, a fuel pressure regulator done.If I had OBD2 I would already be playing with the computer.I keeping this van till it throws in the towel and its computer bites.
A big advantage of the tuning software is that it is a tool , to be used on other vehicles
It not only can tune the computer but it does all the other things that a OBD live scanner can do , test sensors, read codes clear codes, adjust speedo for different size tires and all the other stuff . ...there are also some progs that have Dyno tuning , 1/4 ET times , 0-60 ET , ....
I am a little puzzled in what you are saying . In regard to the 4.3 V6 I have not looked to see if there are any intakes that are better for HP , there might be , and even if you go the route of a performance intake for a carb , there is still a price for that , then you have to buy a carb to put on it , and there is no way to know how much HP gain there is done just by hear or driving it as you can't tell the difference of a 20 HP increase and a 40 HP increase unless you put it on a dyno and measure it at the wheels . With a carb you not only have to buy one you have to spend more labor in taking it apart a few times to change jets , experiment with various nozzle sizes , and metering rods or blocks and then test to see if it made an improvement , Even back in the day when they came with a carb ,, changing to a different intake and a different carb would make a difference in power , and you still incur the cost of those performance parts ,,so that is really not a equal comparison to if a vehicle has a computer or not
.
Buying a HEI dizzy ;How can that apply and be efficient as first you have to buy the distributor ,,there is a cost ,,and the computer is already there all you need is the software to install on the laptop , now that has a cost as well , but it is far better because it has more uses than just tuning , and it can be used on more vehicles than the one in question ,, a distributor can only be on one engine ,,
There is no way to get 60,000 volts out of a coil that is designed for 18-20,000 or 40,000 volts , it not possible to tune an engine to get more voltage out of a coil than what the coil has to offer from the design it was built on, if that were possible the factory would just tweak the tuning of an engine to get more voltage out of the coil,,, If you notice that when the coil starts to degrade in its output the power and drive-ability suffers as a result , there is no way to tune an engine by timing or any other means to bring the voltage output back up to where it was . the voltage output of a coil is derived from the primary and secondary windings of the coil itself , not from any external devices or any type of tuning
With OBD1 in the 90's there is no need to buy any special chip ,,,all the performance tuning is done with the software tool on the laptop ,,those special chips are only for people who don't want to tune the chip them self.
EEPROM chips are Electrically Erasable Programmable Read Only Memory,,,,which is just like the BIOS chip in a laptop or desktop PC ,,it takes a software program that "flashes" or burns in to the memory of the chip a new set of instructions that can only be read , by the computer . the flash process erases the old instruction set and replaces it with a new instruction set , it can only be changed by special software used for tuning , this type of instruction set is called Firmware as it can only be read and not altered unless the tuning software program has been connected to it .
Once you get the tuning software on your PC you can re-tune your chip whenever you want to and not have to pay for anything , because you already have everything you need to do it , This is the dominant method of tuning OBD1 vettes, cameros , firebirds , trucks and any other car that a person desires to tune the engine for more HP and quicker faster times at the track , If you check out the forums for those cars you will see what I mean .
But it seems that we have drifted away from the abs topic
