Greetings from Finland!

My project car is Ford Escort Mk4 -87

Plans to season 2011: Install VEMS and throttle bodies

On July 2010 I got it to the dragstrip and results are: ET 14,32 s and speed 158,73 km/h

On August 2010 we got it to the dyno and results are: 129,9 Kw and 231,3 Nm.

[Escort Mk4]

Engine:

- Ford Galaxy -99 2.3i 16V engine block and cylinder head

- Ford Escort RS2000 -92 cams, exhaust header and intake manifold

- Ford Escort Cosworth T25 fuel pressure regulator (3,5bar)

- Davies Craig electric water pump and controller

- Ford Escort RS2000 ECU (EEC-IV) with Collins chip and EDIS4 with dual coils

My VEMS history :)

I build one VEMS project in 2008, but I sold it forward because I didn't have time to tune it. So it's time to try again!

Old wiring harness and ECU: [old harness]

VEMS external hardware

Injectors: Bosch 0 280 155 504 (~280cc/min@3,5bar?)

Coils: Ford dual coils

Coolant sensor: maybe GM because resistance range is suitable and it's got correct thread

Intake air sensor: GM for same reason

Primary trigger: Ford VR sensor

Secondary trigger: Ford VR sensor, reading exhaust cam at cylinder 4 (I'm not sure do I use this at the beginning at all)

TPS: Keihin TPS (stock Suzuki GSXR1000 K2)

LCD: 20x4 black/green with inverted colors

Lambda: Bosch 057

VEMS related shopping list

Soon I will make order to VEMS shop and I have allready collected some VEMS related items to my project (LCD, knock sensor and wiring harness stuff).

VEMS ECU assembly

Got ECU #3397 [Econoseal connectors soldered] and [underside]

[Black/green inverted LCD screen] and [LCD power on]

[LCD cable grommet and MAP-tube panel mount]

Is this 30V Flyback done correctly? And how about that 4+4 ignition setup. I use EC36 pins 34 and 36, other two IGBT-outputs are now shorted to GND and other 4 without IGBT:s are now connected to logic level.

[MAP, LCD-header, Flyback] and [underside]

Are these wires OK? Especially that 2nd VR from EC36-13 to 2nd LM1815. I measured that EC18-6 (Ch6) and EC18-12 (Ch7) already have pullup resistors (R85 and R86) to +5V.

[2nd VR, TX+RX, Analog Ch5/6/7 and Knock]

Connection from laptop USB -> Belkin F5U109 -> VEMS is working fine =).

Questions and answers

1. I want to be sure with primary trigger config. So, when using 100% same 36-1 triggering that Ford EDIS use, what are correct settings?

use the 4cyl 36-1 configlet (we make sure it's available nov 12)
- toothwidth=10 degrees
- next trigger tooth: 18
- reftooth 0,18,0,18
- EDIS4 = missing tooth is 90 degrees before VR sensor when first cylinder is in TDC.

--> Thanks for advice :)

Story continues... with old connection problem

In 2011, after last editing of this page and after a couple on engine start-ups, I tried to update latest firmware (from 1.1.84 to something that was newest in Aug 2011) before I start to tune engine. Something went wrong and now I don't have connection to ECU thru COM-9. ECU Detect on VemsTune: received ~80+ bytes and send ~5 bytes. So, big guestion is; what to do?

AVR ISP cable USB from VEMS Shop and try Bootloader update? Or am I totally lost with this ECU?

Or throw this ECU away and back to basics with original injection :(. After four years, I have got back some tiny pieces of motivation to get this car back to road and track again =).

Q: Could you elbaborate on exactly what steps you took to upgrade firmware ? did you use firmware upgrade wizard or non-wizard, what firmware did you try to upgrade to ? This information will provide some insight into what might be going on.

Best regards, Dave

A: Because I don't maybe remember correctly all the things that I did four years ago, I can't be sure about all details. It's sure that I have connection thru VemsTune and from VT I tried that Firmware upload from 1.1.84 to last released code. I guess it was 1.1.94 and day was maybe 6. Aug 2011? I have to dig out some old files and notes, if theres some additional information. [Pic of last working FW on LCD]

I have put two indicator LEDs on board, should I see something if ignition power is on?

And TX/RX -bootloader jump/shorting is something that I may try?

Hello Koskar,

So if i understand correctly the firmware upgrade gone bad was already in 2011 and you are now trying to revive your ecu, which now has 1.1.94 to a previous state working state of 1.1.84 ? Or do you intend to start over with a clean slate and new firmware (1.2.31 recommended in that case) ?

Best regards, Dave
