Success Stories

Post by P.Webb »

A sticky reminder:

If you have a running car, or if you get one running PLEASE post yourself to www.msefi.com under success stories. Lance gave us an Alfa section there.

I'm so tired of hearing about Toyotas and RX7s. Lets outnumber that Japanese crap with fine Italian machinery.

Steve R

1983 GTV6, 12v 3.0 (ex 75)
Stock internals, except CB 104/294 cams
CSC manifolds, no centre box, Ansa rear.
modified factory airbox, big BMW AFM with no flap (shortly for the spares box as it only provides IAT)

Megasquirt as per my build doc, with ECU running:

MSnS-Extra-enh-020i9.s19 (to give 12x12 fuel tables and option for spark)

Using Megatune version :
MT2.25 b336 021

I've built the base spark tables & configs using the above, have welded up a spare distributor (must re-assemble it!) and have replacement ignitor and coil (scrapyard VW stuff). Will shortly provide distributor based mapped ignition control - once I have some other jobs out of the way.

Location : Oslo, Norway

1983 Alfa Romeo GTV6

Stock 2.5L engine from a Milano.
CSC headers, Ansa Rear silencer
Stock ignition
TPS from a scrapyard Opel Omega
AFM with flap fully open. Will change to a free flow intake shortly.

Hardware B&G v2.2
Software Standard code v2.98
Tuning Software: Megatunix running on Suse Linux

With Peter Webb's map loaded in the MS, the engine started on first crank. Engine ran smoothly from then on. (I have turned down ReqFuel due to the difference in engine volume) Will work on fine tuning based on this setup. Future plan is to install C&B "stradale" cams.

Followed the instructions generously provided by Steve, learnt the hard way about LJet pins 28 and 29 (why didn't I read the forums all the way through first ??!!) and loaded Steve's sample MSQ file. It runs - but needs a good tinker to get right.

Name:Murray Hickman
Location:Lac Brome Canada
Car 1986 GTV6 2.5L
Engine mods.:S cams,K&N filter,remove AFM,potentiometer type TPS,Total seal piston rings.
ECU:MSII V3.0 fuel only..for now.
Software:Megatune V2.25
O2 sensor Innovate LC-1 wideband

Well finally I feel comfortable posting this info and hopefully it will be of assistance to others attempting this switch from L-Jet to MSII on a 2.5L engine.

To begin I want to thanks all the great people on this board who helped guide me through this sometimes difficult project.

I used Steve Rossers writeup extensively and it helped a great deal.

I ended up mounting my MS ECU in the stock location on an aluminium plate.MS is in it's own enclosure and is wired to the L-Jet ECU connector which in turn is plugged into the stock L-Jet plug.

For my intake I took the manifold temperature sensor from an old AFM and mounted it in a length of 3" exhaust pipe which I then inserted into the stock AFM to plenum hose.I had to heat the hose in hot water to make it pliable enough to insert the pipe.It turned out pretty well.If you look inside the AR flexible hose you'll see that it is a smooth surface all the way to the plenum so if your hose is in good shape might as well use it.

I used a variable resistor type TPS for a Volvo 850 which required an adapter plate to fit the throttle body.I made this out of aluminium plate and it works perfectly.I have tried both Mapdot and Tpsdot acceleration enrichments (which Megatune V2.25 provides ) and I found Tpsdot much easier to fine tune for my application and skills,so having the appropriate type of TPS is really handy if you want to have the flexibility of choosing this option.

My injectors are Greg Gordon's stage 1 replacements for the stock Bosch units.If you have stock injectors my settings should work for you.

I decided to install a WB O2 sensor so that I could really see what was going on throughout my load and rpm ranges.These things are super sensitive to input voltages and ground paths,so if you use one follow the installation instructions EXACTLY.I found that my electrical system was pretty "noisy" so I ended up installing a 20A stereo noise filter on my power lines for both the LC-1 and the MS ECU.It solved all the problems.

I have run about 3200km.(2000miles) and one track day on my MS so I feel confident posting this .msq file

I would point out that in order to get a smooth idle at 950rpm I have to run very rich mixture approx.12.3:1 to achieve an idle MAP of 40 so don't be surprised if yours is the same.

I recently completed a 1200km (600mile) trip through mountainous terrain and averaged 30 mpg.I have definately gained some power (guess about 5-10 hp.) and will dyno my car this summer.I have pre-MS dyno data so should be interesting.

I've kept the stock Bosch ignition for now but as soon as I have a gap between track events I will switch over to MSII ignition control.I'll update once this is done.

Here is my .msq file and a screen-shot of a datalog (right click and "save as" if you want to see it,for those who would like to see what they should look like.

Car: 1991 Alfa Romeo 164S
Specs: All original, no AFM, no TPS at the moment, original Alfa 164 CLT sensor, GM IAT sensor, no idle control (GM IAC stepper setup in the works)
HW: Megasquirt II V3.0, from Glen's Garage; built standard
SW: MSII v2.687, running fuel and ignition with direct coil control; Megatune 2.25.

This engine is currently in a wrecked, but driveable 164S. I will be putting this engine in my Lancia Scorpion eventually, so I decided to 'squirt the engine while it was still in the 164.

I'm running direct coil control (no ignition module, just like the original Motronic system). All 6 injectors are wired to fire at the same time on the Motronic system. Rather than rewire the injectors to fire bank to bank (3 and 3), I decided to run all 6 injectors (16 ohm) from one driver. I am running dual table with the first table running the 6 injectors and the second table setup with 0% fueling across the board. I have no idea if this is electrically kosher, but I haven't had any problems yet. I am going to look into a 3 and 3 bankfire setup when the engine goes into the Scorpion.

Miraculously started on the first try. The V3 board is decoding the stock 60-2 crank wheel (VR sensor) with no problems once running, however it occasionally won't get an RPM signal during cranking. I suspect this is a noise issue because a large portion of the VR sensor wiring is unshielded.

The 164 uses a throttle positon switch instead of a sensor, so until I can adapt a true sensor, I am using 100% Mapdot acceleration enrichment. The Mapdot setup is tricky to tune, so I still have some driveability issues. It's been relatively easy to rough out the fuel, ignition, and enrichment maps. Fine tuning will require some dyno time.
