They share the same kind of 2-wire round connector, so its easy to cross them by accident when performing an engine swap in a 92-95 Civic and 94-95 Integra.

Weird/wonky fuel pump behavior with ambient and in-cabin temperature changesĮx: vehicle runs fine on cold start but once warmed up and driven on, weird things happen and the vehicle can be hard to start back up if turned off or will turn back on after waiting about 10mins or so.Ī burned “Q31” resistor can happen when the IAT and Evap Purge Solenoid (EPS) are plugged incorrectly to each other.

Late or no fuel pump priming after ignition ON.

If you’re experiencing any of the following symptoms, you more than likely have Capacitors and/or IC17 going bad: In rare-rare cases, Caps + IC17 are sometimes not the issue affecting fuel pump operations, but most of the time they are. IC17 doesn’t show any signs of wear & tear (no burning or leaking). The IC17 chip works in conjunction with some of these Caps, specifically fuel pump related Caps. They can also emit a fishy-like smell if you give them a close whiff. They can leak with varying degrees of staining the PCB or having teal colored fuzz build up on their butts and legs. Capacitors are the little round brown vertical standing cylinders sporadically placed around the main PCB.

Part of aging OBD1 ECU’s (Civic/Integra ECU’s specifically) are the onboard capacitors going bad as well as the IC17 chip. All fees include return ship fees for US customers. repair services – bench test / capacitors + ic17 / burnt “q31”įee: $65 for bench testing any reported issues + includes replacing all capacitors and IC17 chip.

This conversion works for stock ECU’s too meaning it does not need a re-programming job to become a manual ECU. This is supported for Civic, Integra, and Prelude OBD-1 ECU’s.

Auto To Manual Conversionįee: $15 for stand alone conversion or FREE if doing a full ECU chip job. The P05 Civic CX ECU in stock form supports a 1-wire 02 sensor but will be updated to support a 4-wire 02 sensor as part of the conversion. The Civic VX P07 ECU with a 1560 board is unsupported. The knock sensor is unsupported with this conversion. I can convert USDM NON-VTEC Civic & Integra ECU’s into VTEC ECU’s, essentially making it into a P28 ECU. non-vtec to vtec conversionįee: $25 for stand alone conversion or $145 if included as part of a full ECU chip job.

I do have several NON-VTEC programs for SOHC + DOHC applications. Stage 3 is a race map, with enhanced programming before VTEC and while in VTEC. Stage 2 is a semi-mild map, with Type-R like programming before crossover & enhanced maps while in VTEC. Stage 1 is a mild map, along the lines of stock Integra Type-R programming. In the old days, EPROM chips would be soldered straight to the mainboard! The socket makes it easy for future EPROM chip swap-outs, say you want to run a different program for instance. “OTP” is One-Time-Program once programmed it cannot be erased. This service consist of socketing your ECU and ‘burning’ a custom map (program) to an ATMEL OTP EPROM.
