I'm going to try this. it raises a question for me tho. If there were a blockage and only a portion of meth was flowing, not all, would meth lights still come on? Would the lights still flash, and proceed adjust my boost, and keep it less aggressive if there were less meth spraying into charge pipe, OR would proceed just immediately revert to map1? Because during my previous logs where my boost is not hitting target, my meth sprayed perfectly fine according to datalog. So doesn't that disagree with my methanol problem being related to the boost target issue? Im not sure of this so please fill me in.

Meth lights will not come on until flow exceeds your Injection Mode value. So to see if you aren't flowing at all or not flowing enough to light the dash indicators, you would have to log meth flow. Also, the transition to map2 occurs as soon as it starts to read flow. But it is not complete until flow reaches the Injection Mode value (which kicks on the light).

For now, try what I suggested (set map to 100%) which will take away one variable from the equation (the boost pressure's effect on meth injection dc%) and see if meth is consistent. If it is, then you will likely have to look for leaks as the source of your issue.

ok, that answers my question. so right now, until i exceed 20% injection, lights are off. it would be maybe a relief for this to be the problem as i can narrow down to the leak, but at the same time, it seems my flow is all or nothing... and when it was all, and consistently all, i was still not hitting target.

but i will do your suggestion tomorrow and report back as the roads are wet today.

spoke to robert earlier. i explained that in those video I've posted I'm consistently spiking around 14 and holding well at 13.5psi bc meth isn't spraying (map1), so I'm hitting target there then... so I'm going to also shut off injection mode for map2 and set start boost as high as 16 and see if i can consistently hit 16psi.. waiting for roads to dry up. looking at 61 and dry for tomorrows forecast. will report back

1) Clogged in-tank pre-filter. This is only really possible if some generic, non-BMW WW fluid has been used for extended periods of time. One obvious symptom of this issue is that your WW squirters aren't as strong as they should be (ie, don't spray all the way up to the top of the windshield.

2) Air entering from the in-line filter. This can only happen if the collars are too loose. If they are, just tighten them up and problem solved.

3) Air entering from the WW squirters themselves. This can only happen if the in-line check valve isn't doing it's job. You can test this by removing it and sucking on one end (against the direction of the arrow). You should not be able to suck any air through it. If you can, you need another check valve. I've only seen this once but it's easy enough to check (no pun intended).

I think every single instance of flow issue that I've seen personally have been a result of one (or more) of these issues. Hope that helps!

I think you might have forgotten one... the use of Meth with gasoline additives

[plague]

turned off methanol mode. ran map 2 at 16psi to see if i hit target boost WITHOUT meth. as far as i know i should be seeing a spike as high as 1-1.5psi above 16 and hold at 16. thats not exactly what I'm seeing here, it looks a little short of where i should be, can i get some feedback.

2nd gear pull.. i did 2 runs just like this following and yielded same result.






ALSO, there is air in my line. Took a clear picture of it as you can see. I am going over all connections now..

If could just make one point it is that my WW retrofit kit has worked seamlessly problem free since day 1 and I do feel it stems all from the user install. No offense as its taken my years to perfect methanol to make it work so well.

I do here the benefits of a trunk mount but Hey different strokes for different folks.

I'd trust logs more then that silly gauge

However, Robert and Shiv have a point if your not hitting map 2 then you wont be seeing the boost you expect. The only way to hit map 2 is to have injection mode exceed target.

Looks like you get a tiny leak or something. Have you primed your WW sprayers? The best way to prime the methanol system is to spray the WW sprayers. To avoid spraying methanol on your car I just cover the sprayers with 2 towels.

just tested the pump. no meth is flowing. in line filter closest to pump is clean and not clogged at all. ill have to work my way through the rest of them. edit: just tested ww sprayers. not spraying.

[Joshboody]

You will have air between valve and nozzles... it purges very quickly when spraying. You can't avoid this due to nozzles exposed. Same with any kit after check valve or solenoid.

your boost looked fine... its not a set boost per the rev range, but changes slightly especially in the top end. You can see this in the 0 and 100% boost tables. Your UT is a percentage of the difference at each rpm

The WW need to be spraying before anything works.

The reason is because your are tapping into the WW line. If the line is not full of liquid it has nothing to suck in but air.

So if you fill the line with meth via priming up and out the WW sprayers then the line will be full of meth. The supplied check valve will then hold that line full of meth up until that point.

A small amount of air by the nozzles is ok. Air from the meth feed to the inlet of the pump is not.

yes i know lol i did the install (maybe thats the prob jk). i feel i did a pretty clean job. but checking the filter before ww spray was silly i suppose i guess the only things that could be the issue are the actual ww resevoir having a clog or the one T fitting that i plumbed into the main line with right?

Well if your WW sprayers arent spraying anything then something is going on there that needs to be fixed. I'm not too good at troubleshooting anything on that side.

Either the T fitting is catching air, the WW pump is not working, or there is a clog or a leak in one of those areas.....

If you are not getting any spray from your WW sprayers, it could be one of two things.

1. A clog in your WW pump filter in the tank.
By reading your thread I believe this is the problem you are having. This was the problem my car had when my kit was first installed. I too would also have flow sometimes and sometimes would not. After cleaning the WW filter I've never had a single issue. To check this remove the T and hold the hose into a bottle and have a friend hit the WW sprayers. You should have flow. If not it is defiantly a clog in the WW pump filter. You should also be able to spray your entire windshield with the spray from top to bottom. If it is barely pissing onto your windshield then there is a clog in the WW pump filter. Just follow my DIY here and you will be ok.

2. You may have the check valve in backwards. Double check by removing the check valve and sucking on either end. Double check that because if its in backwards you will draw air into the system and will not allow the sprayers to spray.

Let us know how everything goes we are here to help. I know cars can be frustrating but just hang in there I'm sure it will end up being something simple in the end.

So it was the check valve hu?

i never installed the check valve.

after install a friend and i looked at this small useless at first sight piece of plastic as just well, a left over piece, an extra 'T' fitting perhaps. little did i know it was crucial. this was likely interrupting methanol flow and thus why i was seeing inconsistent boost as the procede was adjusting boost and pulling timing due to decreased meth flow. we live and we learn and this has helped me to understand how the procede and other components work. at least shiv and i were able to find quite a bit of humor in this. now I've just got to get that ww tank unclogged and things should be running smooth.//

That is too funny!! Good stuff now get out there and have some fun!!!
