My friend check all the MAP line and everything is ok for this part.
But the problem is always here after 2 sessions for the race.

Please could you post screen shot about the advanced setting properties about your USB/serial adapter.

thx

Hi all,

A friend of mine who do hill climbing race have a problem with an usb/serial adapter

This week end is it the race and we have'nt got time to repair the connection before he lefts for the race .....
Of course he haven't an internet connection on the race.

Just after a race session, he has ...

That message looks like you may have corrupted firmware - did you try loading an old MSQ on top of the new firmware or something similar?

You'll want to email the vendor you bought the MapDaddy from directly - I suspect that would be us, in which case the email address is websales@DIYAutoTune.com ...

Ok I made the measure:

U1 Pin#1 = 4.84V
U2 Pin #1 = 4.84V
Js5 = 4.84V

Seems to be the MapDappy default not the setting in MT, reading is always at 416.4 with small variation of the last digit.
I make a depression with my mounth on the MAP pipe with no effect. always at 416.5

I reflash the MSII ...

Are you thinking about Sensor pin#1 ?
And which is the baro output ?

Can make the measures this night for me, this day for you.

Finally find the problem the electric range is smaller than the physical range ....

You were right from the start then!
Again .....

Thx for your assistance.
Now need to solve the Map Daddy problem

LOL :mrgreen: :mrgreen: :mrgreen:

Unusual for sure but it is a variable resistor without electronics inside ...
I use the std 5V Vref like it was assembled in your ECU. (You sold me it in December but not I haven't finish the engine before, to test it).

I can't make any measure today I'm not at ...

Actually, it sounds like the sensor's full scale is smaller than the throttle's full scale!

hummm for me is not the sensor full scale that is smaller than the throttle's full scale.
Because I read the full scale in megatune BUT full scale of the sensor is not reach.
If I decrease the voltage of ...

Yes of course

30 ADC count a closed throttle
1020 ADC count a WOT

You're right but intellectually .... it's making an error

In fact TPS in MT reach full scale before the full scale of TBI and before the Full scale of the sensor.

Thx for your reply Matt.

I have made all your advice about configuring the Map Daddy.

In fact all gauges in MT (Map Engine and Barometer) indicate 416kpa but the engine is not running.
I assembled the Map Daddy to add a barometer correction for mountain race.

I connect another ECU but with the ...

Hi

I have a new TPS sensor.
When I get current at closed throttle I get 30
When I get current at WOT I get 1020

But in MT2.25p3 I obtain 100% of TPS before the real WOT of the throttle.

How I can fix this ?
Do I need to reduce the voltage of Vref or Vtps ?

Thx
Pat

Hi

I have a problem with my Map Daddy.

Always at 416kpa (both of the two sensor). Map and Barometer

I have installed the sensor, put the right setting in sensor calibration section.
Selected the right Sensor in the configurator.

I don't know what happen.

Any Idea ?

I beleive he thinks to increase from 1 to ....
4 squirts being for smoother idling.

Thx U Matt.

No I run pump gas Injector (from VW mexican beetle).
I think that my NB send bad value or may be not function correctly because I read on MT 0.45/0.5v on EGO meter but the exhaust gas mixture feel rich.

How to know the correct InjOpen Time ?

I start my engine with the advocated value (1.0ms) but Idle speed is smoother with 3ms.

How can I determine the "correct" value ? Measure ? Calculation ?

Txh@all
Pat

yes seems to be done one day

Thx for your encouragement

Cut in one piece, the "base" of the TBI

On the 2 pictures above you can see the height of TBI Vs IDA.
You don't need to change the manifold if you plane ...

Would it take more time to port new runners or to modify those other TB's, fab a linkage, sync them, find some air filters that fit, and then tune them? :shock:
Sweet looking engine BTW. :D
Also liked the CAD models.- Awesome. I actually modeled my fuel rails before I made them. Nerds of a ...

Yes I know the CB Perf casting.

But I'm running IDA on this motor before so I want to re-use the manifold.

I don't want to spend a lot of time to make porting again.
