ITEM 1.                            SECURITY AND ISSUER

This filing is Amendment No. 1 to the Statement on Schedule 13D (this "Amendment No. 1") filed on behalf of Passaic River Capital, LLC, a New Jersey limited liability company ("Passaic") with respect to shares common stock, par value $0.001 per share (the "Common Stock"), of Enerpulse Technologies, Inc., a Nevada corporation (the "Issuer").  The address of the Issuer's principal executive offices is 2451 Alamo Ave. SE, Albuquerque, New Mexico 87106.

ITEM 3.                            SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Item 3 of the Schedule 13D is hereby amended by the addition of the following:

"On January 26, 2017, the Issuer entered into a securities purchase agreement (the "Purchase Agreement") with Passaic River Capital LLC ("Passaic").  Pursuant to the terms of the Purchase Agreement, the Issuer issued and sold to Passaic a senior secured convertible note in the aggregate original principal amount of $37,500 (the "2017 Note").  Passaic used working capital to purchase the 2017 Note.

Unless earlier converted or redeemed, the 2017 Note will mature on January 25, 2020 ("Maturity Date"), subject to the right of Passaic to extend the date under certain circumstances.  The 2017 Note bears interest at a rate of 12% per annum, subject to increase to 18% per annum upon the occurrence and continuance of an event of default.  Interest on the 2017 Note is payable in arrears on the Maturity Date in shares of Common Stock or cash, at the Issuer's option.

All amounts due under the 2017 Note are convertible at any time, in whole or in part, at the option of Passaic into shares of Common Stock at a fixed, initial conversion price of $0.005 per share (the "Conversion Price"), which is subject to adjustment for stock splits, stock dividends, combinations or similar events.  If and whenever after the closing the Issuer issues or sells, or is deemed to have issued or sold, any shares of Common Stock for a consideration per share (the "New Issuance Price") less than a price equal to the Conversion Price in effect immediately prior to such issue or sale or deemed issuance or sale (the foregoing a "Dilutive Issuance"), then, immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price.

Subject to the Issuer fulfilling certain conditions, the Issuer may require the mandatory conversion of all or any principal portion of the 2017 Note (accompanied by a cash payment to Passaic of an amount equal to all accrued and unpaid interest and all interest that would have accrued on such principal through the Maturity Date) if the closing price of the Common Stock for any 20 trading days during any 30 consecutive trading day period equals or exceeds $0.03, as adjusted for stock splits, stock dividends, combinations or similar events.

In connection with the Purchase Agreement, the Issuer entered into the Registration Rights Agreement with Passaic pursuant to which the Issuer agreed to file a registration statement with the U.S. Securities and Exchange Commission to register 125% of the shares of Common Stock issuable upon conversion of the 2017 Note.

The obligations of the Issuer under the 2017 Note are secured by all of the assets of the Issuer and its subsidiary (the "Collateral") pursuant to the terms of the Security Agreement which confers on Passaic a first-priority security interest in the Collateral, subject to permitted liens which may have priority over such security interest.

The foregoing summaries of the Purchase Agreement, the 2017 Note, the Registration Rights Agreement, and the Security Agreement do not purport to be complete and are qualified in their entirety by reference to the complete text of the Purchase Agreement, the 2017 Note, the Registration Rights Agreement, and the Security Agreement attached hereto as Exhibit 7, Exhibit 8, Exhibit 9, Exhibit 10, respectively."

ITEM 4.                            PURPOSE OF TRANSACTION

From the date the  2017 Note is converted into shares of Common Stock until January 26, 2020, Passaic has the option, in its sole and absolute discretion, to purchase 10 shares of a new series of preferred stock of the Issuer for a purchase price of $10.00, which new series of preferred stock will have substantially similar rights, powers, and preferences as the shares of series A preferred stock, par value $0.001 per share, which were issued to Passaic on July 27, 2016; provided that the new series of preferred stock will provide that Passaic will have right to appoint a majority of the members Board of Directors of the Issuer.

Any alternatives that the Reporting Persons may pursue will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices for the Common Stock; the financial condition, results of operations, and prospects of the Issuer; general economic, financial market, and industry conditions; and the investment objectives of the Reporting Persons. Except as set forth above, the Reporting Persons have no present plans or proposals with respect to any of the matters set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D."
