The car started fine but after 5 seconds or less you can see the fuel injection increase and the car stalls out?

No matter what I do the car dies each time. I have no correction maps enabled.

Any ideas?

Ideas: trigger noise, improper ignition and trigger setup, excess fuel, not enough fuel, improperly configured sensors, improperly wired ignition or injectors.

Thanks just it, you need correction factors to compensate for the different conditions, an engine needs different fuel amounts for each temperature value, a cold engine needs more than a warm one, i would bet that you're fuel injectors might need cleaning, have you done this already?

Also, do you have you checked for vacuum leaks?

Well I did wire up my E6K. Other then the fuel injector harness being wired up incorrectly (The injector harness came prewired) it started up right away.

I've also helped install a E6X that started right away.

I sure hope I did not wire something incorrectly. I double checked the ignition and CAS wiring. I can check the fuel wiring some other day. I doubt it is a wiring issues since it started and idled at 750rpm and sounded fine for like 5 seconds. Something odd thought.

Thanks for the info.

Really?

I thought not. Maybe I guess I am wrong. (Figured it would start and I could just throttle the gas to keep her at speed) It idled for a few seconds and as soon as I hit the gas it goes dead.

The E8 map is just a copy of my E6K map. Identical settings but with the obvious changes in software.

Vaccum leaks. Nope. I did a quick check and did not notice any. At least there is none without having a look under the UIM. Vaccum leaks can be the biggest culprit.

Thanks,

when you start it up open the trigger diagnostics data page, watch for 12 in the trigger since last home. It might just be me but I have huge trigger noise issues running an e8 off the stock cas, that manifest in an impossible to fix idle. I would also turn the coolant correction map on and make it a bit richer on the low end.

Ahh... you should've said that before, if you can hold it there at idle and it will stay is one thing, if the car is idling on its own and shuts off for no apparent reason, thats another.

If you can hold it there and when you put your foot down it shuts off then it might just be a matter of tuning the compensation maps, throttle pumps, fuel map, and what not.

Sorry. I am not very clear.

I turn the car on with no correction maps and not on the throttle. It started ok and sounded great then died within 5 seconds. I could see the vacuum decrease and the fuel injectors increase.

I turned the car on with the same parameters and tried to hit the gas. Died just as quick.

I did install one of those magnetic coils that you see attached to wires of PS2 controllers around the CAS wires.

At this time I do not suspect fuel map or compensation map error since it is just a copy of my E6K map that worked for years and was tuned by steve kan. I did turn off the throttle pump off as well with the same outcome.

Thanks for your help guys. I appreciate this. Its always hard to figure things out through text rather then actually looking at the issue.

Thanks,

I did have the trigger diagnostics data page open and since I really didn't know what numbers I was looking for, the numbers were meaningless to me and I forgot what i saw already. I will have to check again.

Take that off, thats only going to cause problems.

And i suggest you put a base map in there that DOES have correction factors, its better than having none. The reason your car is doing what its doing its because when you start it there's a "primer fuel dump" that happens at startup and that amount of fuel is whats keeping you going, but after it runs out your map and compensations dont put enough fuel in there to keep going.

Try downloading one of the base maps i've got in the base map thread, that closest matches your injector size, dont worry if the injectors are a little smaller, that will only mean it will be rich, but thats not a bad thing. Let me know your injector size and ignition setup and ill point you to one.

I've never tried to import an E6K map into an E8...

...but, the E6k can only run "batch" unless you have it set to / 1 ?
Most E6K maps are set to / 2 ?

Is your E8 set to full sequential?

Ok, so this is an E8? yeah, im sure you need to tune it right.

What is your injector size?

IAN

iTrader: (3)

Yes it is set to sequential.

The import didn't work very well. I had a friend "Nik" just interpolate the values in.

I think maybe there may be a timing issue. I will not get time to work on the car for another week so I will try then.

A quick check of timing with it locked to -5° showed the first indicator (Red) light up. Strange since I did not change anything and left the values the same as the E6K. I doubt I had it set that way for 4 years on the E6K!

Thanks

550 and 1600cc. Yes its an E8.

Claudio RX-7

iTrader: (1)

There's your problem right there. The Leading Mark is the YELLOW one, at -5 degrees. You're timing is not zero'd in right and its way off. You have to go back and use the Yellow mark, if you look at the pulley standing in front of the car, the yellow mark is the one first from the right to the left.

If you send me your map, i can update it to E8.

IAN

iTrader: (3)

Ya. As I went to bed last night I was sure that was the problem. But how would that change. I never took the CAS out and I used the same ignition settings as with the previous E6K.

Claudio thanks for the help. I do have the E6K to E8 already converted. Thats why it should have just started right up.

I will keep and update on what it is.
