Caterham R400 K-engine MBE map Help

I forgot to say, before (when nothing was going well) I had also backfire from intakes.

Now, only a little if I go back to 71 fuel gain

Oh, is the backfire from the trunmpets or exhaust?

I can look at your map for any reasons, but it won't be until the weekend.

From the trumpets, some "little" (but scary) bangs (not now, but if I put back the fuel gain to 71)

From the exhaust I have flames, only on warmup. (or bangs if I put back to 71)


Anyway I'll go to Portofino Lotus7 meeting this weekend (keeping the 85 fuel gain, as the car runs good), than back to mechanical to fix some leaks from the gearbox and differential service maybe.

UPDATE:

Now the car runs great.

Only one strange thing: we set to 1000 rpm x 85 fuel gain x 11 kgs for couple

After the first run the car went to 1200 rpm and about 13 kgs per couple of trumpets. The load site still remained 0 with 0.45v.

I don't know if it happened due to some correction map or simply the coils cleaned up.

Aniway it starts good and runs good and worked good for all the weekend.

Should I have to lower the minimum to 1000 or I can leave it like that?

8654 also worked for me... and than I removed the pin control.

I haven't checked the A/F yet because in these month I haven't had one free minute to work on the car

First step was to kick the distributor with double VVC coils (wasted spark) --> Works, too :-)

By the way: Do you have different R400 maps from the rolling road? Would it be possible to provide them to me?

VVC coils.. It sounds very interesting

Is it difficult to fit that coils?

I was interested on that mood, but I've read "somewere" that will not work good for high revs.


Anyway I still don't have any RR map, only my original with more fuel gain
