Hi Honda ppl, this is my first post.

As a prior Honda Owner (1992 Civic EF boosted) I felt I could be a contributing part of this community.

I came across a 'boost solenoid' thread online that made me want to contribute here.
(https://honda-tech.com/forums/forced-induction-16/boost-soleniod-help-2600218/)

Anyway, I have recently designed and built a highly functional multigauge controller over the last 8 months. It started off as a boost gauge, cuz I wanted an 80mm electronic gauge and felt I could build one cheaper than buy one.

Well, 'feature creep' crept in and now it's about done, bench tested, and I think 'ready for the world' so to speak. I am looking for additional potential test vehicles. Perhaps forum members might be interested!

First a summary, cuz the detail is really kinda techy and reads like an AEM advert...

Ok, The device is a multigauge controller, 80mm diameter, dashboard mount via gauge cup. It offers a bright 4 Digit readout and an independent analog LED sweep, so u can view 2 sensors at once. You get Vac/boost gauge up to 4bar+ (45psi) , user scalable continuously to any full range down to 22psi. Tachometer, AFR linear wideband or narrowband, EGTs and Voltage.

Also, multi map closed & open loop EBC, electronic indash BOV tuning & boost pop off, 2 multiparameter aux. relay drives, a spool dyno logger and a turbotimer.


There you go...what do you think?

Below is the full detail for those who might want to try it out. It's not for sale, yet, but I plan to send out trial units. Testers can keep the units. This open to the Honda Community.


FULL DETAIL:

Key Features:
1) Tune out on throttle Turbo surge even below WG crack pressure! No normal boost controller can do this.
2) In Dash tuning of the BOV (Pneumatic or elec) for better throttle response via precharging the intercooler and halting off throttle surge.
3) Display dual data sets at once, choose from Boost,EGT,AFR,RPM. Better data, better performance!
4) Indash spool up dyno for your turbo tuning. How good is your tune?
5) Allow user to activate (online codes) only the desired features thereby reducing the upfront costs. You decide what you want.
6) All features active for 22hours runtime, so u can TRY BEFORE you BUY.


Text Desc: An attractive 'Dial' multigauge controller, dashboard mounted ( with incl. HW) via 52mm thru 80mm universal gauge cups.

DisplayTypes: Analog 20 fullsize LED sweep & large 4 digit*display within an 82mm diameter display.
*
Default permanent features:
3 or 4 bar Boost gauge, EGT display, Voltmeter, Turbotimer, NB AFR, continuous barometric correction.
22 Hour runtime Demo of all features activated before automatic downgrade.

Upgrade features:
Wideband/Lambda AFR, Programmable Auxiliary drives, E-BOV dashboard tunable sensitivity/duration*control with POP off overboost limiter, E Boost Control with launch Traction control, Spool Dyno, Tachometer display. Tachometer data are available to boost control & auxiliaries even if Tachometer display option not activated.
Features can be purchased and applied before or after the demo* period expires. A new Demo period 'feature' can be also purchased to assist any resales.
*
Display Capabilities:
1) Displays Boost (PSI/Bars), AFR (WB, lambda*& NB moving avg), RPM, on either Sweep or Digital. EGT & Voltage on digital.
- EGT display requires a 0-5V linear K type input. K type Tcouple & linear Preamp, 4mV/C, module are Additional.
- Temp range to 2200 F , > 1200C, programmable parameter relay trigger in aux. drivers, see below.
2) Peakboost/Peak RPM / PeakEGT features. EGT displays in F if boost 'PSI' units active, Celsius if Boost 'Bar' Units active.
3) Independent Analog & digital display combos, eg. Analog*sweep Boost & Digital RPM
4)*Analog sweep capable of* (2x270)* 540 degrees*resolution in Vacuum/boost mode.
5) Indicators for dual aux drives & turbotimer countdown.* Backlight.
6) Optional Opening ceremony displaying settings and active features.
7) Dimmer
8) Audio visual alarms
*
*
Control Capabilites:
1) EBC with 3*closed loop PID*& 3 open loop maps. Up to 4 bar. Optional Continuous barometric correction for hilly terrain (with dual sensors)
Note: Precision Solenoid Frequency range adjustable over 15Hz-100Hz, in 1Hz steps. Higher Freqs require lower PID Integral factor.
2) Electronic BOV control (can drive mech. BOV via vacuum canister) , includes protective, user set, overboost pop off option.
3) Gearbased Boost traction control
4) Twin auxiliary drives with TPS,Boost,RPM , EGT& AFR parameters. Latency response control. (0.1 sec incremental )
5) Turbotimer up to 10 min. Digital countdown option. Turbotimer will use Aux2 relay drive, either feature preference is menu selectable.
*
Benchmarking Boost performance (dyno) & precision calibration.
1)*8 data point dyno, capturing timed boost spool to a user set pressure after each gearshift/vacuum transition.
2) Precise one touch*ambient*calibration (during Open Ceremony/motor off) to provide for Temperature & elevation conditions.
This is required when unit is first installed or*if the MAP*sensor is replaced. Each unit is therefore custom calibrated to match individual sensors.
Optional user recalibration*if*super accuracy is required for a particular environment,* at the race track perhaps.
The system remembers the*calibration data.
*
**
Human Machine Interface:
Similar to Turbosmart2 with 2 button control of a hierarchical*4 Digit menu system. Simple & efficient plus tactile & audible feedback .
One touch/hold swaps Performance/Urban EBC & BOV control maps. ie. Scramble boost
One touch for Peakboost/RPM/EGT.
One touch for Dimmer toggle
One touch for alarm acknowledge, eg. sensor over/under acceptable range => connection error or failed sensor.
One touch/hold for menu entry/exit.
One touch for dyno mode reset or*cancel.
*
*
Noteworthy
The programable aux. relay drive system permits* the addition of* external shift lights, relays (water injection/nitrous) , *or boost/EGT level warnings/triggers.
Further the configurable aux. system can SOLVE partial Throttle turbo flutter with the addition of a 1/2" recirc. solenoid valve, parallel to the BOV.
Additionally this 1/2" valve ( Via EBOV ctrl) can augment the mech. BOV response providing very fast (sub 50ms)* response with resultant smoother throttle response.
Continuous baro sensor shares EGT input line, only one can be active. Menu configured.
All drive lines switch to ground.
Low cost purchase with 22 hours runtime of full features, you choose the permanent desired features online. Security code entry, no PC link required.
Construction & Durability
Based on a microcontroller system board, using modern SMD devices and some through hole components. ROHS compatible. Pb free.
Rear mounted 6 pin miniDIN connectors and*10-24 threaded hole for*machine screw*mounting onto Universal gauge cups.
6-32 Machine screw ground lug.
Remote sensors.
Optoisolated tachometer.
Shielded vs Automotive transients/load dump.
Tolerates 24V jumpstart & reverse voltage.
Electronic autoreset*V+ rail fusing.
Powder coated metal housing- various colors. Compatible with Universal gauge cups.
Acrylic faceplate.

Sounds nice, any pictures?

Sure:
The pigtail wires only exist in this prototype version, for reprogramming.
The Sunlight Bright Display overwhelms the camera a bit, knocks off the focus....(Display dimmable at night)

is that a freakin tuna can? LOL
gotta love prototypes....

Shall we just refer to it as a marine quality housing?


But, more seriously, it seems that grounded ferrous based housings give better electromagnetic protection than, say, aluminum. Something to consider when both emitted EMI (high speed switch & ringing) and received EMI (elec. noise/cell phones) must be limited based on SAEJ1113 auto EMC standards for electronic sub assemblies.

Ferrous materials handle both radio frequency shielding and electromagnetic/magnetic shielding. Aluminum does not handle electromagnetic or magnetic shielding.

Higher production levels will justify tooling a die to stamp housings including prepunched holes.

Can u tell me what your motor setup is like? Do u have an ebc/3 way solenoid or mbc, what kind of BOV, running EGTs, running a linear wideband?

Do u have a tps, can u tap your ecu tach signal, manual shifter?
