I decided to re-write the entire code and make it simpler.

You turn the mode select knob to one of 15 settings, it selects that mode while idle, then starts when you press the obligatory start button. It fits on the smaller chip, but I'll need the next larger chip if I want a segmented LED display for viewing the mode.

This is some pimp shit.

Did i see something about an led display??

Yeah with 2 extra chips and a whole bunch of wires it can display the mode number (up to 99). I coded them like mode 0, 5, 10, etc just in case I needed to stuff a bunch more modes in. The thing is I don't have the 7-segment LED's, nor do I have those controller chips.

LMK if you need offset data, etc.

It took very little time to rig it, but forever to get it how I wanted it. And I'm still not done. Since I have ADD I can only do an hour of work per day.

I'd not recommend plastic cylinders, since most are polyethylene and gasoline or spirits will eat it up. There is a surplus science place close by, so I get "chiyrex" for a decent price. I definitely recommend getting the plastic anti-roll rings for them, that woulda saved mine.

I think mineral spirits has enough difference to toss off my raw flow numbers, but for matching purposes it will be fine. I'll just have to measure weight using specific gravity to get the correct CC/min.

You can rough and sleazy it by using a control injector of a known rate.

That's what I did before I had my injector driver. A clean 240cc, and it worked out darn close. I want to send out a handful to just get flowed so I have a good baseline to compare to.

Send them to me and I will flow them on the flow bench for you.

Just got everything 100% today. For $50 this cdm 255hp pump is wicked.

With luck I'll be spitting injectors out by the dozen in no time. I have a few days off soon and the weather is supposed to be great.

Sweet!

good i need a set..

can you throw up your code? im getting into embedded programming and want to see some practical implementations.

HiProfile · « **Reply #39 on:** March 12, 2012, 06:31:49 PM »

I'd rather not at this point. It's just BASIC that's been modified a bit. On the picaxe.co.uk forum you'll find a lot of sample code. Arduino code is probably closer to what you're looking for tho.

Okay, slight snafu. I ordered 2 sets of the 1k injectors from 2 companies (to see who had the best service)... Turns out both use the same drop-ship warehouse, found out I ordered 2 from 2 companies, and both were cancelled.

So word from the wise, if you have to check on customer service, wait for one to be delivered before ordering a 2nd item!

HiProfile · « **Reply #41 on:** March 14, 2012, 11:50:17 AM »

Orders were all corrected.

Soon I'll have 4 sets of "1000cc" injectors for you nogs. Their actual flow will be ~880cc, just like Injector Dynamics.

Any thing bigger in the works?

HiProfile · « **Reply #43 on:** March 14, 2012, 11:57:55 PM »

Yes, but that's up to Sewell. If he doesn't get his controller soon, maybe not. I know he had found something.

92CXyD · « **Reply #44 on:** March 15, 2012, 08:05:59 AM »

What is the turn around time if I send some Delphi 780cc injectors to test?

HiProfile · « **Reply #45 on:** March 15, 2012, 01:03:39 PM »

I'm moving from the 11mm rail to the 14mm rail asap, and I won't have adapters for them for a few days/weeks. I want to get sewell's controller tested & shipped before I do much else.

Once I do, they'd ship out the same or next day I receive them. I'm in WI, so it would be a week round trip.

Fuck yea Tom lmk when your ready to drop them. Might be try running no coolant and just run alcohol with fully filled sleeves.

I may need a set by May for the PNW meet

Russ you realize 1600cc is enough for 700hp on E85, right? Or maybe you do...

No E85 for me E10 or E15 maybe

Planning on maxing out the He351ve

very interesting stuff........ seems pretty complex compared to other stuff ive seen.

HiProfile · « **Reply #52 on:** April 11, 2012, 11:55:53 PM »

With Tom's help I made it a bit more complex than I first imagined. I'll be posting some pics and maybe a vid soon.
