Hi...I have the Mini shown in the picture. I bought it second hand. By looking at the tune that was loaded it looks like it was running semi sequential.
I have a completely stock Na6 ( 91 1.6 jdm) with auto transmission. MAF delete with iat.
Can somebody please let me know what All of the jumper settings should be for a first start.
Also because it has a/t it has a vtps which i should be able to use ( worked with speeduino)
Thanks.
All the manuals for the Mini are on the site: https://www.mslabs.gr/en/product?product=78 - Click Manuals and download the manual for V2, which explains the jumpers. The jumpers are the same across all versions of the Mini.

Hi.. I followed your link but can't find Manuals on site.
Interesting. Try it on a computer instead. Looks like the mobile site is missing the downloads.
Yes indeed. I can now access the Manuals.Unfortunately they only give a brief description how to set jp10 and jp11 to sequential. I need to know how they were set as default. Also tps,tach,cas and vref jumpers.
@Reverant does the 90-97 1.6 ms3 mini contain the circuit for a VSS input? Is it possible for me to pull a VSS signal from my cluster and wire it into my mini and if so which pin would I use?

No. You can use the tableswitch or the Flex input though.
Ok, Ill investigate the tableswitch or flex inputs.
I did some more reading last night after posting and was hoping since the same ecu is shared for the 90-97 1.6 and the 94-95 1.8 that pin 1M would have been wired for the stock VSS signal on the 94-95 harness and I could just use that (similar to how I upgraded my 90 to sequential injection).
Does the MMS390979495 just ignore the VSS signal in the 94-95 1.8 harness?
@Reverant please see my previous post. I own a v3 MMS390979495 and Im curious how it handles the VSS for the 94-95s. Im wondering if I could use the same mechanism in my 90.
If not would I need to add a pull up resistor or anything to the tableswitch input or can I just wire the VSS from my speedo right in?
Just wire the VVS from the speedo to the tableswitch input, no pullup is required. Some users have reported that the NA VSS signal is generally very noisy.
Really? Damn. Is there anyway to filter the signal? I was hoping to get boost by gear working and to maybe keep launch control from messing with me between shifts.
Hi All... first post and thought I'd wake up a sleeping thread....
I've got an MS3 Mini PNP v2.0 installed (today) in my late NA MX5 1.8, with the 3 plug ECU. It was registered in 1998, but may have been built late '97 - not sure. It's a UK car. The MS3 install is a prelude to further tuning in the future.
I've got it all wired in and it all seems to work... except for the fuel pump. The pump doesn't run unless I earth (ground) the Fuel Pump connection in the diagnostic box. If I do that, I can hear the pump running (constantly when the ignition is on) and the car starts/runs for a few seconds. The wideband is attached and calibrated, but isn't actually in the downpipe yet, so putting that in the pipe might make it run a bit longer. However, I'd like to fix the problem that's stopping the
It's been suggested to me that some of the very late NAs have different pinouts - I wonder if I have an NA/NB changeover car and one of the pinouts is different from what was planned on the ECU?
Does anyone have a pinout diagram for this ECU - the quick start instructions were very helpful, but there's no pinout diagram. I can then compare it with my wiring and see if it's different.
The car started and drove into the garage yesterday, before I began the swap.
So I found out the answer to this, with a bit of help and thought I'd update the thread in case it helps anyone else. There's a jumper on the board which requires a different setting according to whether or not your car has a factory immobiliser. I've fixed it the other way by swapping the wires in the multi plug between pinout positions 1U and 1V. I proved it with a quick and dirty jumper wire between the pins at first. Once you hear the fuel pump prime then it should work ok.
Hey Folks - long time lurker here and very green in regards to standalone ECU tuning. I figured it was time to make my first post.
I recently installed a Mini MS3 w/OBD in my 04 MSM. Reverant has been a huge help answering my barrage of emails and general newbness. But I figured I reach out to see if any one else has installed or worked with one of his newer ECUs. This version is a mix of standard MS3 plus some MS Labs magic. For instance idle control is managed by a secondary processor. The TS screens are completely different for what most people typically interact with.
Current state:
Dead cold start - difficult cranking but it does eventually catch.
Open loop idle - settles in nicely and is smooth.
Closed loop idle - is where I am having difficulty, but only when starting from cold. The idle oscillates wildly until the temp comes up then it slowly smooths out.
Warm start - catches without extended cranking both Open and Closed loop idle being good
I even drove her the other day on a maiden auto tune voyage without any drama, albeit only for 10 miles.
I am purposely withholding what Reverant thinks might be the issue with the hope that some seasoned forum members would chime in with suggestions/ideas where to look. Even though this ECU contain proprietary MS Labs technology, the theory of EFI engine tuning still holds true, right?
edit:
wideband: Spartan 3 w/LSU ADV via CAN
elevation: 6545 ft (1993m)
It took three attempts to start the car started today, log attached.
The tune is essentially the base tune plus some very brief auto tuning.
