would it be fine to create a second fuel table with zero values and have a hidden switch that sets the ecu to that table to stop those nasty car theft's from happening?

or maybe the idle fuel set well so the thief can start the car and feel great about breaking the law..., but as soon as he puts ...

Heres the tune file and a datalog the was done before it started leaning out the whole map.
I notice when i scroll through the datalog, when its reading around the 0.03 to 0.29 mbar range in the fuel/ign tables, its saying 15psi+ on the sensors screen for map??

was running in open loop as only has the stock o2 sensor in place, was being tuned with a motec o2 sensor in a second bung in the exhaust (not hooked into smanger or anything for auto tuning...)
Everything was fine for a few hours of tuning, and had had been driving fine on a old tune for a few days ...

Had been dyno tuning a H22A S300 Turbo for a few hours, and it was going very well. Tuned upto 6psi and drivability was fine on the dyno.
Then turned off the car (had done so a few times for a few breaks during the dyno tuning, smae as usual) started it up and all of a sudden all the tune was ...

maybe ya just need to put a new battery into the rolumator if ya keep getting errors...
Might not be enough power to keep the rom image in place when you turn off the car...

yea same here, nothing chagned in the car apart from pulling off and putting back the distributor cap and spark plug leads, then it just started happening,
done data logging and the map sensor seems fine, no unusual readings.. just kept on cutting engine power when boost came on.. also the revlimit ...

Yo dude, sounds like the same sorta problem i've been having, just seems to randomly set a rev cut at about 3000rpm, (hasnt happened for the last couple of days though, but was real bad last week, every 20 mins or so it would happen)

I dont have the launch control option, but sometimes during ...

I've left mine for weeks without turning the car on, works fine every start, i got a couple of spare cell batteries in the glove box and have an old crappy laptop in the car incase the romulator battery runs out, just pop a new battery in and upload the rom again, sweet for another year :)

Would be ...

Nope, using a 3bar, everything was working fine until now, tune is good (running 1bar at around 450hp) car was driving fine for a few months, just got this happening as of last week (actually the problem didnt happen at all yesterday)

Is there any particular wires or connections that when they are ...

Got a funny problem, S200 system was working perfectly (p08 ecu), then I went away for the holidays, and to protect the car from theft I removed the distributor cap (bit hard to drive without one), then when I came back and put it back together everything was as per normal with driving, and ...

its a P08 Ecu (S200 hondata) in a 92 prelude, turbo (odb1 model, no need for any harness)
incase that info helps...

When I go off throttle at sometimes I get the O2 sensor error poping up,, only at off throttle driving at high revs, the tune is pretty perfect at normal driving, and the error only comes up once in a while.
Anyway of disabling this error?? or what parts of the tune should I be looking at altering ...

Anyone got the recommendation for the cold start enrichment value for a H22 with 720cc injectors?

Just wondering what exactly the boost cut does, does cut spark, or turn off the fuel pump or injectors?
Wouldnt it be a little worrying if you were boosting 20psi with the boost cut set at 21psi or more, and then all of a sudden your fuel got turned off??
Wouldnt it be safer to cut back spark ...

GT3540 Turbo (.82 exhaust)
