Doe this make my car automatically run 10's then?

 

Endreight,

I'm trying to find an ECU for an NB1, year 1998-2000. I was looking with interest at the ECUmaster Emu Classic as a worthy contender for a good fit in my self-wire standalone project.

The problem I'm finding here is that the ECU doesn't have base maps for my NB1, and I'm finding it difficult for any tuning garage to either provide or build same. I would be very interested to know how you went about your tuning, and your approach to finding base maps.

Many thanks

 

I Have a Maxxecu mini in my nb, and for a basemap i just emailed them and asked for a basemap, and i got one, pretty sure EMU can send you one aswell. either way its not too difficult to put one together if you want to yourself.

 

EPP,

Thanks for your contribution. I will request from ECUmaster of base maps. If they are unable to provide useful mappings, what is involved in building these from scratch? I would imagine that 100s of numbers would need to be entered in order to create maps. Maybe there are default figure patterns that can be used.

Thanks again

 

it really isnt that bad to build a basemap. heck you could even copy a VE/Lambda/ignition table from another type of ecu and manually put the numbers in. its not harder than putting numbers in an excel document.
once you get the car to idle and the spark is where its should be you can road tune it so you can get it to a dyno and get the rest done.

 

Have you already purchased the ecu? If not I would highly recommend going with a different ecu maker, one that will be able to actually offer support.

If you really want to continue you could probably build a base map based on basemaps from Haltech/Link/ and other standalones that offer basemaps. It would be a bit tedious. Especially if you don't know what you are doing.

 

Thanks for the replies. I haven't yet purchased an ECU, as I want to be confident that base maps can either be sourced or built by myself before committing to a particular model.

I've investigated the Link Monsoon unit; unfortunately, it doesn't provide knock sensing support or include an O2 controller, both of which are supported by the Ecumaster Emu Cassic or Black units.

I'm open to suggestions of other ECU options. The car will not be used for track or high performance & high revving use. That said, some performance and efficiency gains are sought.

I'm considering replacing the stock crank trigger with a 36-2 wheel, though I've been told that this is only really of benefit to high performance tuned cars.

Thanks again to all for reading.

 

As mentioned before, a base map is not rocket science and wont take too long to put together. have you looked at a fuel table before? you typically have to axes: RPM and MAP, which determine how much fuel is required at the current position, which is marked on the map in real time. you then change the number up or down to give it more or less fuel. some ecus have afr 14 set as default when firing up a new ecu , and about 10degrees of timing, so technically if you get it to idle then the rest can be done with autotune. My tuner told me that he appreciates when people get to know the ecu and software and get the car running, it saves him a lot of phone calls about minor issues.
You wont detonate your pistons into the stratosphere just by fiddling about at idle. You can do this without a base map. and since its a 4 cylinder 1600-1800cc the tuner could technically send you a map for another car entirely with similar specs, and just change trigger offset, type of ignition and injector size/deadtime and you should be pretty much ok aswell

 

Haltech S2 can do all what you want, has pnp harness, and has a basemap.

 

I have been looking up the ECU tuning principle procedure, and am starting to gain some appreciation of the work.

From what I understand, there is an AFR target map that needs to be initially programmed. These maps appear to be almost or entirely the same for any spark ignition car. The aim is to adjust the VE map cells so that their values match the target values in corresponding AFR target chart cells. In adjusting the VE map, the target AFR figure for each cell should appear as a single listed item. I do have a query on the VE cell adjustment process. The VE of the engine over the entire engine load and rotation speed is determined by the breathing efficiency, and therefore the design of the engine, so how can we change the VE cells, and therefore breathing efficiency, by simply changing cell values?

Regarding the ignition map, timing is set for each cell in a load vs engine speed map. Dwell angle, injector delivery rate is then declared in the ECU software.

I am considering installing Audi R8 coil-over-plug ignition. The MX-5 NB1 functions on the wasted spark ignition model. Can standalone ECUs be instructed to fire on an individual plug coil basis, to coordinate with required cylinder ignition timing? Is a coordinated spark sequence even desirable or necessary?

Thanks again

 

pretty much sums it up.

yes a standalone can run sequential spark and/or injectors if you use both a crank and cam angle sensor. The nb1 has both.
