Smart injection

[Richard L]

Have you tried turning off the gauge (hence the system), the boost pressure should drop. If you get a CEL, you can use the jumper link marked "DR1" to stop CEL triggering.

Hi Richard,

I am sold on pre turbo injection, car makes 1.5 bar boost in first five gears, it has never done this before!
I'm keen on the combined MAP FI system as it is the logical progression, giving a more accurate picture of injection requirements.
I will try the jumper, luckily my X-guage allows me to read and clear faults.
I think that my problems with the failsafe were caused by by me not understanding the system more than anything else! It is a steep learning curve for a novice.
It is good to get to grips with everything before tuning.
I only got manifold air temps of about 12 degrees above ambient on the way home (at some speed), I would not believe it if I hadn't witnessed it, lol. Usually it is a heatsoak situation that climbs and climbs above 40 over ambient. I have had the coolant temps over 100 on a hot day before, but it was rock solid 82 all the way! This will certainly allow more power to be made with tuning and still have les stress.

Cheers!

ECU pin 39, wire colour green, Intake manifold pressure sensor.

ECU pin 72, wire colour blue, Injector 1 (can't remember if this is pos or neg, will check, think it neg)

ECU pin 68, wire colour Blue, BCV

The list above will be something for you to venture forward. Get the best of the system.

Now that we have sized the water nozzles and the trigger point. Gain is set to 1:1. The water/methanol will mirror the fuel duty cycle all the way to 100%.

Play time starts now.

Can you get 99% pure methanol locally? make sure they are in seal container. 25L canister is very common.

waiting patiently to see how the km/l and power change.

Hi All,

Yes I have got pure methanol and distilled water from Reagent Chemicals, They deliver in sealed 25l containers, think I might need more soon
Am looking for a more local and cheaper source too.

Cheers!

Thank you for the info.

Do you have a more comprehensive detail of the ECU pin arrangement. I like to draw an outline of the ecu. If at any time you can unplug the ECU and take a few pictures of the pin-out side, I will be able to make an drawing from there. Don't forget to tell me where pin 1 is.

One more pin that will be very useful. A switched +12 for the red wire of the gray harness. This will make the wiring of the grey harness a deal deal simpler by not having to slit open the vinyl sleeving and pick out the red wire out of the bunch.

The price of methanol ranges between ?16-?25 per 25L. How much are you paying?

How long does your 8-litre tank last?

I cannot wait for you to get rid of the over-rich fuel maps. I like to see a leaner and meaner machine in the making.

[Kapt. Q]

I think that I paid more (45-50 delivered), it was a 'stop gap' measure untill I found somewhere else more local/cheaper.

The car has become quite the alchoholic, lol, it drinks heavily, I will have a better idea today of consumption rate vs petrol and mileage.

Yes that map has been bugging me for a while, it must suffer bore wash when cold.

Tuning next week if I can get it in with them.

Good source of methanol: bio-fuel suppliers.
