Wet Manifold and Typhoon Assistance
Turbo Mini Forums

Finally one of the most important aspects of any ecu is support, I dont know if theres a backstory here so im not goint there and am certainly not inquiring, but if you feel the support isnt there, move to a different ecu and cut your losses, especially if your throwing dyno time at this, your probably close to the cost of another ecu already.

Alan is sending the new Spartan, so I should receive it this week. That will allow me to capture one channel of AFR which at this point will be fine.

The only time wasted so far is mine, although I did take it to a tuner for a session several months ago.
Yes, at some point a decision needs to be made, as other have suggested, that there is no value in spending any more time with the system. I have a JBperf Microsquirt that needs a harness and a few other details sorted.

I am not quite there yet, as it is a learning experience for me. I plan to call them as others have had better support via phone. Unfortunately I will be away for work for a number of days which will halt any progress.

Got a reply from SC-Delta. Still trying to decipher how it applies, progress though...

I've problem of "engine died at a stop sign" too.
I think that the idle speed control is the key.

I've modified some idle control setting on my MPI Typhoon ECU.
First, in the "Idle speed control variables", enlarge "idle control TPS Enable Threshold[%]" from 0.78 to 1.56.
Second, reduce "Dashpot dRPM Trigger" from 1000 to 5.
All of these setting will make the Typhoon ECU enter Idle control a bit earlier to prevent engine from stall. Also, you can try to disable "Over-run fuel cut-off".

I think that the "Main spark advance" of base mapping did not take control of spark advance when idling.
The Idle control spark advance is controlled by 2 setting:
"Idle control Base spark advance" and "Idle control proportional spark advance".
The first one is "BASE" referenced spark advance when idling.
The second setting provide spark advance correction in accordance with the RPM error when idling.

You can try these setting and, hope it can resolve the issue of "engine died at a stop sign".
PS: MY ECU is Typhoon 2 (not Delta 400) and, the version of SXtune is 2.2

Currently, I am struggling with another engine died problem.
My car equipped with A/C.
When idling and A/C on, the RPM dropped and engine died.

Kevin:
Thank you for the post. I was away for a week with work and then another week for a family vacation.
I am trying to work through things with SC.
We were sidetracked by getting a check on fuel pressure, so I ordered a gauge. My implementation is in an LWB car whose tank can present issues with surge. Fuel pressure was steady even at low volume and hard stops and acceleration.

They have had me turn off "over-run fuel cutoff." It seems to have helped, but there is still some faltering when coming to a stop.

I will investigate the other settings you mentioned. Unfortunately I am like an old dog with a bone and still keep chewing on the problem when it may make more sense to move in a different direction.
Thanks again
Terry

So with the adjustment to fuel overrun, the car does not die at stop signs. The RPM does drop pretty far, but with no idle air valve to temper the change to off throttle I am not sure how much should be expected.

SC did have me test the fuel pressure and with 5 or 6 runs over three days there was little variation.

But I am seeing this in the AFR with the Spartan2


All other variables are relatively stable, but the lambda fluctuates., making me think that there is an issue with the Spartan2 or soke manifold leak I can't fine.

Is there a way in Mega Log Viewer to change the time units displayed?
I have not made any other changes as suggested by Kevin's post , yet.

So you have sorted the ignition timing

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

I would not say it is sorted. Turning off the over run has made it drivable to the point where I am driving it to work.

At least with the 30 minute drive to work I am able to log data and review it. There are still some inconsistencies I don't understand.

I need to review the physical installation again looking for manifold leaks or other sources.
And I need to check the settings and sensors variables. For instance, this morning I noticed a difference between the mechanical coolant temp gauge and the value being reported through SX Tune. I have changed MAPs in and out so many times, perhaps I lost the values for the Rover MPi style coolant sensor.

I know I saw them posted either here or on one of the megasquirt forums.

It is probably close enough that I think I feel comfortable driving it the 200 miles to the rolling road.

I guess we are spoiled in the UK. I know of 3 rolling roads within 10 miles!

I should clarify, it is a 200 mile round trip so only 100 miles distant.

And there are other RRs closer, but none have experience with A-series Minis or at best very very limited experience.
This person actually owns a Mini and has experience with SC Typhoon ECUs.

So I don't know if you are spoiled in the UK or those of us in the US are just at a disadvantage...

Spoiled, or just all rammed into a tiny island

if your not running an idle valve try leaning out the cells he engine runs in as it drops down to idle this will have the side effect of being a little lean on over-run at low rpms but it will help catch the idle better and you may be able to reach a compromise.

So I am back at this after having been sidetracked by a brand new rack failure, issues with brakes and the Typhoon choosing to disconnect intermittently.

I actually drove about 15 short trips with minimal issues. The temperature was relatively warm as it only now has turned colder. I was already to start driving it to work to collect some data and now the fancy modification to the fuel tank is leaking...probably just needs tightening
One thing after another...

I guess I am still over quota on questions at SC as I wanted to buy another USB-Can cable to leave in the car, but no response from multiple emails.
