Had the coolant temp sens code. I read up on it and it appears to be associated with wsgt position set to high. Drove earlier with no more codes.

OK I believe the problem stems from your meth injection being set at 25 when you are flowing nearly 75.

I believe when the discrepancy is very large it will go into a limp mode because you are now "over spraying"...

Set injection mode to 70.

Best advice is learn how everything works/connects and purchase each piece individually to construct your own kit. This will save you a lot of time and money, trust me I'm coming from experience :P I used that awesome setup @robc1976 has to dictate how I rebuilt my own kit. I ended up having a kit that is mostly comprised of Devils Own components with a BMS FSB and 2.2G tank.

copy that, will go for a test run. Thanks!

I did build my own and with the help of the guys on here the kit itself works great. It's mostly all DO with a aquamist flow sensor. Now I just have to dial everything in

btw Jeff, I've seen some logs with debug 7 is that an old parameter no longer used or should I be logging that as well?

That is likely your problem. 98% sure

It's been a while so I honestly can't remember.

Throttle
Boost
CAN Ignition advance
CAN Actual Air Fuel
CAN Fuel Trim
Intake Air Temp

Those are priority. All the other sensors can be used for diagnostics but aren't 100% necessary to datalog.

[scottp999]

Why do you have boost higher on map1 than map 2? Does meth not transition to map2? should it be reversed?

OMG!! I actually got a little scarred lol. What a beast!
This log showed a max steady meth flow of 66 so I dropped inj mode to 60.

How does it look Jeff?

I just went with what Rob @Vishnu told me for those values.

[qubansailor]

Everything look good minus minor fluctuations in meth flow around 3 points. Is that normal or should it be more consistent? Anything else I could do to fine tune?

Perfectly fine.

I would set meth injection mode to maybe 58. It will vary up to 5% or so.

I knew the 25 setting you originally had was too low. There is a safety feature for too much methanol built in.

You could another +5 to OL Fueling too and see how the fuel trims respond. They are in a safe area though so it's not 100% necessary.

Yeah everything i read before said to keep it at 25% to start but obviously that wasn't working out, lol. Cool, will try OL at 80 and see what happens. Thanks for checking it out Jeff. No techs are available at vishnu right now.

[qubansailor]

BTW Jeff was that +5 OL for both maps or just map2? What is the target fuel trim to look for?

You could do both maps. It wouldn't hurt.

In an ideal world you want trims at near 0% give or take 5%.

However 10-15% is acceptable.

[qubansailor]

So I ended up doing a fuel flash yesterday stacked with the procede. AFR and trims look much better! Dropped OL to 50% the only thing I see is the ign cor is kinda high. Any thoughts?

after reading all this...... I already knew I wanted meth one day which is why I perched the CP with two bungs from topgearsolutions but geeze, you guys just lit a fire under my butt.. I want one now!

OP- Awesome info and thanks for sharing

Thanks to everyone who contributed! I would also suggest you go for the bigger tanks. I have a 2.5g and with all testing I've been doing. I'm going through a tank in a week, lol.

Thanks for the heads up-I saw a post where they were testing bigger (4-5gal) tanks.. I may go this route. Im shopping some kits/parts now!

That may be a good idea. My 2.5 gal tank goes fairly quick. I think i may have to get off the pedal a little bit. Its annoying having to fill up the tank so often, lol. Not to mention the person i bought it from installed the level sensor a little high so i have a low fluid light at half a tank, smh

Are you logging without meth and then logging with meth shortly after without time to adapt?

The meth log actually looks ok. I wouldn't worry about the 1 ignition correction and there was no instance of ignition reduction from knock.

No meth however did have 2 knocks. That could have been because you previously drove on a methanol map then reverted back to a non meth map without enough time to adapt.

Or it could be an indication that the octane is too little for the boost your running.

Eitherway, stick to 1 or the other and if your going to log meth then no meth or vice versa keep in mind they will need a few runs to adapt.

Makes sense waiting to adapt. How do you tell knock from the logs?

3 degrees ignition drop at once. It's not necessarly actual knock. It sometimes is a preventative measure from the DME to avoid knock. It drops timing 3 degrees at once to avoid potential knock.
