3 capots d'avance je demande à voir

Moi je pencherai peut etre pour l'ecu, j'imagine que l'ecu d'un 90ch est différent d'un ecu d'un 115ch (carto différente ?).

Si il avait fait un swap alors il aurait du swapper également l'ecu, car mettre un moteur de 90ch sur une carto de 115ch ça doit tourner comme une patate.

Par contre je n'ai aucune certitude dans ce que je dis, je n'émets que des hypotheses.

Arretes de te prendre la tete, lorsqu'elle sera roulante on se fera une sortie avec Personne dans un parking de supermarché, on fera des runs cote a cote et on verra bien si on te mets 3 capots d'avance

I have been playing with the maps for a while now, and tested a few setups. Net result so far: 9 HP / 15 Nm gained
In the picture, black is stock Euro 90 HP 1.6, Red is "BaktusSpeed RevM5" chip

To unmystify:
I have made a socket with switches, so I can change maps "on the fly". This improves on the relative accuracy of my Gtech data.

First, I tested a modified stock ignition map (see earlier in this thread) to familiarize myself and prove that I had found the right map.

I made a 1Mb EPROM containing the stock map, "BaktusSpeed RevM1", the Japanese 1.6 maps, and stock 1.8 maps. I found that the best results were with the maps from the 1.8l.

So I made "BaktusSpeed" RevM2, 3, 4 and finally 5, where I took the maps from an 1.8 L and added 8 degrees ignition up to 5000 RPM, then tapering down linearly to 4 degrees at max RPM. The results were quite OK for a total amateur, I think..

Now I'll take a break, and drive my MX-5 around for a while, summer is short in Norway, and you must catch it when it's there.

One day, I'll find the RPM limiter....
