Once again valuable....thank you..so i guess if i understand you correctly....the map says 50... Which would actually be 25..due to wasted spark...? When i measure the advance at the crank...can i just divide by 2 or does the gun need to be set for 8 cylinders?

The map has 50 set in it at the higher rpm

You're correct. just a thought, have a look and see if the gun has a two stroke setting on it.

I don't mean to be negative, but this assumption is a little optimistic.

 

So assuming this is the plug and play solution...what sort of readings will i be looking for on the lambda scale? 

 

There are settings in SX Tune which will need to be changed for Spartan lambda controller, assuming this is still what SC sells.

Also i have heard that there is a self learn facility..anyone know how to do this? 

 

I would also suggest to initially use the wideband to monitor AFR and make small incremental adjustments, before turning on the autotune function.

The critical thing would be to download a backup of the existing map you have and then every time you make a change, make a backup.

 

All the information is in the online help within SX Tune. I found this a little difficult to use as I was making changes as I wanted the SX Tune program full screen. I made a PDF of the online help. It is a few versions old by now, but the basics do not seem to have changed.

 

Somewhere along the way in this thread I got thrown off and assumed this was an SPI. I apologize, if I contributed to any confusion.

 

I would be careful trying other MAPs as your configuration would be different and require adjustments in SX Tune. I could share my MAP with you, but I am using the Rover crank trigger and Rover coolant sensor. Certainly it is good to compare different MAPS, but I would check the configuration closely before loading it into the ECU.

Thanks for this...i have ordered the lambda sensor from sc. Have found a rolling road some 300 km from me..and will try to get the tuner there to help...if this does no good then......i am ripping it out and going back to dizzy and carb...and will sell the lot...i should never have done this so far away from england....however i was told more than once that this was not rocket Science...

Its not rocket science, stick with it, Just make sure all the hardware is fitted correctly and is tightened down, You don't want any movement from brackets etc. If the team with the rolling road is any good they'll have no trouble downloading the software from SC and setting it up. It really is simple, but it is more time consuming than quite a lot of ECU's. If you've managed to get it to run on one of the supplied maps sufficiently well enough to get it to the rolling road it'll work. There are too many people who want to overcomplicate a lot of issues. Stick to the basics and you'll be fine.

[tmsmini]

I would agree with sticking with it.

If you have it running at all, it should not take much to sort it out.

 

Check the basics before looking to the SC components. In my case, even though it was a new engine, there was a bent valve.

We have about 3000 miles on the car now and just went to a Mini event last week and added another 300 miles. It could still use some minor adjustment and I would like to make some refinements to the installation.

 

I am just finishing installing a second ECU into a car for ignition only.

So quick update...lambda in situ..need to do some welding in y piece..in meantime am checking everything again. The emissions came back with 2000 ppm for HC.! Thing is plug 4 looks ok..1 and 2 are the black ones.

Just checking...my coil pack is correctly connected to the plugs??? Or?

Looks fine to me, 1 and 4 fire together as do 2 and 3. I keep saying this but you must be absolutely certain the exhaust is completely gas tight. If you're not sure how to achieve this read my previous posts number 23 in particular. If it's not gas tight fitting the lambda is a waste of time.

I am based in Poland myself, can dig out any local help you need and can act as a translator just in case. Feel free to PM me if needed.

Just wondering, where did you mount your ecu and where do you run your cranktrigger wiring?

[Ann-Wilson]

So will be checking the exhaust again..
For seal...noticed a little soit out of the seal at back....ecu is in car under the passenger dash rain..its lhd. Crank trigger runs over the thermostat housing as in the instructions..however i built a mount onto the lower bolt of radiator housing and route it away from alternator and any relating parts.

Any air ingress with make the lambda think the mixture is lean and will therefore richen it up, at this point, the lambda becomes a liability.

Any update to this? I have the ignition only car running pretty well, so I am back to the full SC kit car to try to fine tune the idle.
