Ok so what I have trialed so far.

FlexFuel wire floating or grounded (Not Game to try +12v unless told to do that)

This does appear to switch tables (Set table 2 very rich at idle and can see AFG gauge change when grounding pin 6 of the MicroSquirt)
It seems to be able to switch on the fly (No ...

Hi Guys

Could anybody explain the flexfuel switch setup for the MicroSquirt please. I have read the manual and trialed it but it does not appear to behave as expected.

Manual says
when the FlexFuel pin is High, the dual table usage is set to VE1, AFRTGT1,
when the FlexFuel pin is pulled Low ...

Wow reading that it does seem I am unclear in my answer so I'll try again.

1. It is at 100kPa with the engin not running and Mirorsquirt powered on
2. It used to aftter starting only go between 20 and 40kPa while driving
3. I replaced the brake booser pipe
4. Now it is 100kPa with engine not ...

The brake booster pipe had a small crack in it and once replaced the map now reaches 100kpa again.

Pardon me, but I am not clear on this. When is map reading 100 kPa?

Hi Ken

It starts at 100kPA with the engine not running and Mirosquirt powered on, once started it drops to around 20kPa at ...

Hi Dave

It does start out at 100kpa but I think I have found the problem. The brake booster pipe had a small crack in it and once replaced the map now reaches 100kpa again.

Thanks so much for your time, I guess I need to tripple chack everything when things don't go as expected.

This is the MAP and vacume advance connection, it is hard to see where it is on the manifold due to the cramped space. There is a T Piece just out of picture spliting to both.

Ok here is what I have got, due to space it is hard to get a clear picture.

Brake Booster Connection

This is the other side which is easier to get a photo of, just to the left of the green knob is where the MAP and Vacume advance are connected, just on the other side of the intake ...

How have you derived the vacuum feed to the MAP sensor?

Hi Dave

I have it connected direct to the inlet manifold, it also goes to the Vacume advance on the distributer. The Brake booster is also connected to the inlet manifold.
(Sorry am not near the car atm)


The inlet mainifold has two ...

Best idea yet!

Ken

Done, not sure if it is usefull but stops me looking there

Hi Guys

What is the nomal range MAP for aturally aspirated engines? I think I have a problem as mine only ranges between 20 and 40 yet the tables go right up to 100?

I have stable ide and have tried VEAL which has done a great job at making the buggy drivable however it seems very slugish and ...

Hi Ken

Thanks, I did not think it would but that gauge kept catching my eye and knowing Murphy personally (from Murphy's Law) I thought it better to check first.

Thanks Again

Hi Everyone

I am running fuel only on a Ford Pinto 2.0L, 4cyl and the Ignition Advance gauge does not match the timing light. I have set the base timing in the Trigger Wizard and the car is starting and has now got a stable idle, just the Ignition Advance gauge does not match the timing light ...

Sorry should probably mention erasing flash goes through no problem, verifiying is where the problems start (if that is relevant)

Thanks, I have tried but am having no success.

I have followed the instructions here http://www.useasydocs.com/details/usv3code.htm but to no avail. I get "ERROR: Unknown status received, s=0x3E" or "0x00" or "0x01" or "0xE1".

It runs for around 20 min restarting a few times then hangs on one of ...

Firmware is v3.830

Soory is MircoSquirt V3 (New one purchased from EFI Source as full kit)

I have a Mirosquirt (new) connected up, went through and calibarted all the sensors and all good. Started flow test using injector test mode but now stuck in that mode, each time turned on the test mode is started but no communications to microsquirt, says offline. I have tried disconecting ...

Thx, I have that covered as the Central Point Injection (CPI or CFI) Throttle Body has one built in as well as a fuel pressure regulator.

Thx will recheck that diagram. So the MircroSquirt will be the correct choice for my needs along with a wirring harness and the sensors for MAP, Coolant, IAT and cO2. Have I got everything covered or am I missing either parts or some important piece of information. I just need reliable running at ...

Thanks, I thought I would be using the hall effect triggering? The module can be seen on e bay (either on the com, com.au or co.uk sites) by serching "Ford Pinto AccuSpark" which shows a hall effect pickup and a magnet. The manual you linked to does show a hall effect sensor so I assumed this is ...
