Help! 1.6L 16 Valve Injector Specs?
« on: December 13, 2005, 11:49:11 AM »
Can anybody tell me the specs on the injectors in a 16-valve MFI injectors?  Specifically, pounds per hour rating, opening and closing time in milliseconds?

I doubt that they're the same as the injectors in an 8-valve!

Injected fuel volume:

38 - 48 cc/15 sec. (1.28/1.34 - 1.62/1.69 US/Imp. oz/15 sec)

CJ, Did you know that the Jap Helly Hansen model  Escudo have bigger Injectors and bigger Throttle bodies and a different ECM  ;)

In the states we use cc/min or Pounds /hr
They should be aprox 17 PPH and have an
opening time of about .8-1.0 millisecond

So Bob, are you setting up and tuning the
MegaSquirt ???

Have fun, Wild

Do you know the impedance of those injectors? I noticed in the Jimny manual that it has high impedance injectors. It is also MPI with a MAP sensor.
Wild, did you get any opening times for the 8V injector at different voltages?

Darrin - the 1.28 - 1.34 Oz per 15 seconds that cj posted - that's 19.2 - 20.1 pounds per hour.  Hmm.
Yeah, but I'm really seriously looking at jumping in with MegaSquirt-n-Spark all at once, and using the factory harness (I have an ECM connector, I am adapting to the DB37).

The V3 PC board has high current drivers, and flyback stuff all on-board.

The MegaSquirt never powered the 8V injector,
I think the 8V injector to be lowZ and 50 PPH

Opening times are pretty typical, and the baseline
used is aprox 1 millisecond, anything lower than
this is questioned by the MegaSquirt program, which
uses the opening/closing time as part of the overall
time in Ms of the injection pulse, giving too long of
an estimated o/c time will be of little trouble with
stock injectors, but with large capacity injectors,
could really cause an over rich idle

Tell me more  :) By the way I learnt that the earlier 16v has a bigger intake and AFM and it gives more performance  ;D

At 19 to 20 PPH would explain why the
16V turbo conversion works so well with
the stock ECU and injectors.

V3 board sounds like the way to go, I use
the current limiting settings to skip the
resistor packs, so far that seems to work fine,
time will tell, but the transistors don't even get
warm so I think it's working OK

Does v3 still use the Dtype? usually they are only 5A rated so its pushing it a bit if you run high rpm a lot.

I will test my spare injector when I get a chance but I don't have a power supply that can supply enough current at home.

I can get you TBI Ohm readings,
TBI isn't in much use now   :(

I'm picking up a H/Hansen 16v Motor a 4spd auto next week to put into a mates Sammy I'll check it out for sure and let you know. ;)

TBI injector is 0.8 to 1.8 Ohms, I was looking for the impedance of the 16V injector. I haven't got the specs for those.

According to the FSM, they're somewhere between 10 and 17 ohms...  Can't remember exactly, but definitely considered Hi-Z injectors.
