Calibrations coming along well?
What is the lowest temp the EFI has started up in?

Lowest operating temp so far has been 11 degrees..That was our low temp here so far this year. This morning it is 17 here and the Pinz fired right up for his 43 mile trip to the shop using the cold start MAP I had programmed 3 weeks ago when our last cold snap hit.
The benefit of this system is simple user programming. I am really going over the top to get all of these cold start MAPS programmed. It's simple, if it's super cold out and you have a hard start issue just open the glovebox, pull out the programmer and key to the cold start values. Go to the values that are close to the outside temp and raise them a little at a time until the engine fires. Once this has been done once in all operating temps it never has to be touched again on your engine.
I am trying to offer a pre-tuned kit thats very thorough and completely understood by us for ultimate support later. I do have to put a cap on it soon as I have HUNDREDS of hours in this work so far and at the price the kits are being sold at we'll never make our money back (even at this point)
If things continue to be long and drawn out we'll either have to adjust the prices or the purchasers will have to settle for a less tuned system.

Nope, the highest point on the east coast is only 6,600'...
The system uses a MAP sensor for compensation, so to this point we have not had any issues with altitude.
Keep in mind that I build all sorts of aircooled engines that have used this system, those engines have been shipped all over the world with this same EFI system in place, adapted to their particular application.

It should do ok, I am using an EMS 8860 computer on my Beck injection set-up in my Pinz and have great results above 6000' 
Most EFI computers will compensate for altitude up to 10,000', but they cap it off there to prevent use in aircraft. To calculate altitude they use the MAP sensor, some systems also use a seperate Baro sensor.

EFI kit core issues
Jake, I understand the latest design does not require us to send stock manifold cores back. Do we need to get something altered on it prior to installation of kit. Also what about the crank shaft pully (any modifying of it for pickup sensor).

712M, EFI any time now, diesel trans, line-x, charcoal paint, the list goes on & on, and a smile every time I drive it.

The only mods you gys will need to do is the mofdification of the crank pulley. we'll enev include the drill bit you need and a template for drilling the pulley correctly.
Work continues on the kit, I have some time critical projects here at the present, as soon as they are gone I'll take the Pinz FI kit to the next level and get the dyno work out of the way.
Jim, Do you have an extra Plenum for FI?? I'd like to test your design Vs mine for some baselines on the dyno next month...

What about the oxygen sensor(s) on the exhaust header(s)? Not a big deal,
but still a modification that needs to be considered in the overall scheme of
things.
If you go back to the first posting in the thread, the features of the system are listed. I don't see any mention of an oxygen sensor. That must be an oversight, since somewhere in the middle of the thread, Jake does suggest driving over to a muffler shop to get the bung installed...
Jake: You mention the possibilty that you may have to ship the system without being able to test at all extremes, and that the end user may have to use the progammer once or twice. I would think this would be a fair compromise - if someone has the skill to install your EFI setup, I think it is safe to assume they can muster the additional skill to run the programmer. My 2 cents...

EVERYONE WILL have to do some programming- thats a guarantee because no two engines are exactly the same.. The other variable is fuel, in every state the fuel is a tad bit different, especially states that have oxygenated fuels.
What I am doing is going totally out of my way to get the huge majority of tuning done for the end user...
The benefit of a programmable system is having the capability of manipulating the engine completely, unfortunately this is also the same negative aspect of such a system.
Everyone that buys one of these systems must do the research to understand EFI, how it works and learn how to do the required tuning. I'll be able to offer support with the systems, but can't hold everyone's hand!
I have learnewd that the first year of having the system installed is the only time that changes need to be made and thats just due to the user's climate and is pretty much only related to cold start values.
I'm doing a ton more than I should be to make this a bolt on, closely tuned system, but I don't want anyone to misunderstand and think they'll never have top use their programmer- its a certainty that tuning WILL be a necessity.
when the tuning is done, throw the programmer in the glove box and leave it there, thats where mine has been for 2 years in my Porsche.

Udate?
Hi Jake,
Do you have an ETA on the kits? I know that there are a lot of people waiting to hear.
How about an update please sir?
Thank you,

Most all "In Truck" development is completed....
We now lack the Dyno development that will prove exactly what I have been able to create power and efficiency wise as well as how engine temperatures are impacted by the upgrade. For this testing we'll be testing a freshly built bone stock 2.5 engine with optimized carbs Vs the EFI arrangement.
I have three obstacles to overcome before this can be finished:
1- I have been invited to the new TV show "Blow it up" that will air it's first episode prime time on Speed in June. We have been given 21 days to build a complete car and engine that can withstand lap after lap of drag race punishment with nitrous oxide being dumnped on top of it. we'll be competing till the weakest car/engine dies so until this is over I have dropped everything as a chance like this is a once in a lifetime experience, plus I love to blow engines apart.
2- I have to wait for a chance to get the engine bolted to my new dyno... We have kept it wide open since I finsihed it in January working with an inventor that has a very new and exciting engine technology concept that is almost developed. I can't bolt a Pinz engine to my old dyno due to the design, so we have to use the new lab for this development to thoroughlly log the information and prove what we have created.
This is my new lab, where the EFI systems will be finally developed, its rather extensive as you can see.
3- I am still held up on the final production quality intake plenums for the system. My fabricator left to go work for Penske Porsche on litle notice so that forced me tofind someone else to produce the plenums and that has not been easy to do at the same price that we were going to do them for at the same quality. These plenums are holding everything up at this time.
I have been working on this development when I have a chance, Pinzgauer development and engine work are not my primary objectives here as they supplement what we do, so I can't take time away from my primary work to finish the secondary work up, at least not when we are crazy busy...
A lot of things have happened throughout this development that have made it more difficulot and time consuming to create than I ever expected. In hindsight I never would have started this development, I would have made a decent system for my Pinz and called it a day, BUT we now have purchasers for the systems and I have an obligation to keep my word to the Pinz community and those that have placed deposits on the systems as well. Know that I will be dedicating all my spare time after the TV show taping to getting this development completed.

JAKE,
i for one appreciate everything you are doing on this project.
yes i'm chomping at the bit to get the unit but i understand your difficulties. and have confidence when it is sent it will be right.
i'm having carb issues but that will be fixed ( ordered float sync. tool ) to keep in Pinz running.
keep us informed.....ie reminder about the veiwing of the tv show sounds like fun good luck with that.
thanx again Pat
