Haltech E6K map to E8 Map. Batch VS SEQ

E6K map to E8 Map. Batch VS SEQ
I had my E6K map converted to the E8. Obviously the E6K was set to Batch. Currently my E8 is set to Sequential/Staged.
Unknowingly I was beginning to question my fuel configuration and since i think I may have issues with my Wideband I was not sure what was happening. It appeared to be running lean. Car idled fine and looked to be around 12.5. (I don't think that was in coolant correction mode either.)
I called haltech and my understanding is that if you convert the E6K batch mode fuel map into E8 running Sequential you are in theory running half the fuel.
Is this correct. If so how come I could get the car to start and drive what appeared to be normally down the street? (That one squeeze of the throttle hitting 9psi probable was not a good idea!)
Any ideas. I know I am posted alot of questions lately

So for anyone else doing this kind of conversion of maps from batch to sequential, would it be reasonable to just double all the fuel map and retune from there?
Haltech also mentioned the injector dead time, and tuning that into the battery correction map. Most people don't really do this on the early haltechs, and the dead times just get absorbed into the fuel map. I guess this will just make the doubled map richer, not necessarily a bad thing.
I am really surprised his car would have run at all with 1/2 the fuel delivery required...

That doesn't sound right, but I don't kow anything about the K.
I was under the impression that batch mode would toggle between the 2 injectors, which wile not identicle to sequential in that its not timed thats the same amount of fuel. I think what happening is its getting to the staging bar where the k would be firing both secondairy injectors at the same time and firing them sequentially. I think thats where youve got half the fuel you need, which would explain why it drives normally untill it hits the staging bar.
Of course I could be way off, I am not an expert... Claudio is

Thats why i suggested to leave the fuel settings as they were in the K to get it running. Then if you want to retune it completely later on as sequential you have your work cut out for you. Either that or find a reputable tuner.

They did mention that I would not notice a difference between batch mode and sequential. Sequential has better fuel control. Must be more noticable in piston motors.
Nik was the person who converted my E6K map to E8.
I was confused about my car idling and driving. Holding the car in idle at 3500 rpm it did go lean.
I am still lost in injection lost time and not even sure how you program that aspect of it. (I'm not even sure on that end of iseq njection ° stuff. Maybe that was what they were making reference too.)
So needless to say tomorrow I'm going back to batch. And spend another day to see why I have such a difference in my wideband indicators.

Yep, all I did was convert his ign and fuel maps over from e6k. Just used linear interpolation where the points changed.
Ian, I guess the plan is to go back to batch for the MCO school? Once that is over you should try to get the seq inj mode working, and then we can do a before/after comparison of the fuel maps to figure this thing out.

If it's " / 2", then it's actually backwards - the E8 would be running TOO MUCH fuel, approximately twice too much.

Well I drove around with it set to batch mode /2. I can't see a difference from Batch mode and sequential but my wideband seems to have a error from 1A/F to 2A/F between logworks and the display. I can't get consistant readings and I can't stare at the logworks program during accel fast enough.
Just gonna have to wait for nik and his wideband.
