Not Revving Past 4k

Hey all

Had a search through other posts but couldn't find any that explained my problem.

95% of the time the car drives perfectly. This morning she wouldn't rev at all, wasn't flat footing it, just normal everyday driving style and she kept cutting out till i shifted into 3rd and than the problem went away. Happened everytime i stopped at lights ie 1st and 2nd coughing and spluttering than 3rd and above normal. Checked that the AFM is plugged in, boost guage reads 12 PSI with no boost spiking running a normal bleed valve.

When i drove home from work earlier today (sore back, don't ask) she drove like nomral. Only happened when i was almost home and gave her a bit, wouldn't rev past 4K and kept on cutting out. Looked at the boost guage and was sitting at 12 PSI.

Got a mate round to show him and car drove normally. Revved past 4K and pulled strongly through all gears.

Also it would seem that my bleed valve isn't working. I have the thing shut so that it should be at the stock boost pressure but she's still reading 12 PSI. Could that be it ???

Finally i recently installed a Hybrid bolt on intercooler kit. 600 X 300 X 76. Now my bonnet won't shut properly as we had to remove the centre bit to install the intercooler. We knocked up a peice of metal to hold the latch in place but it won't pop the hood unless someone is pulling it up and it moves up and down in the wind as i am driving

Any ideas as to these problems?

Thanks

I remember my 3SGTE was so shit, in stock form, it just got worse and worse, till finally, I wondered if it would even make it the short drive to the workshop where I was having an aftermarket ECU installed.

I never thought about it much again because the car was alive and double the power of ever before after the tune. I was half expecting to be told the engine was dead.

I am amazed how many people have problems related to running rich, as I did and don't just get an aftermarket ecu of some sort. SAFC if you have a low budget.

One thing leads to another when you run rich, you'll use more fuel, you'll block up your cat, etc.

Just get an safc and a tune, if not one better and get a full aftermarket ecu, make sure you have NO boost leaks. get rid of you bleed valve if you have it shut.

Now it won't rev past 4.5 at full throttle. Starts spluttering and coughing. 3/4 and she revs to about 4700 but keeps cutting out. At half throttle however it revs out to 7 no problem. Any ideas as to what could be the problem. Installed some iridium plugs today but this problem is annoying me.

      I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies.

      It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest.

      Use text replace function to auto-link to referred threads?

      Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks!

      It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers

      Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...
