RIP kit... Ghetto style!

[cherry1809]

Yip, Got bored again so got the hacksaw out. I basically swapped the intercooler top hose and the throttle body elbow over. The rest is cut and shut. Doesn't look pretty but it works. The idle control valve is now Plumbed into where it was before but at the top of the intercooler. Not ideal but it seems happy.

lol i like it, did you notice any difference in the spool up with the RIP kit?

[cherry1809]

Haven't tried yet. Did it at ma and pa's (where me tools are) and wasn't warmed up enough on the way home.
Main reason for this was I was trying to find out why I was getting what seemed like fuel cut. I've cleaned EVERYTHING with carb cleaner so we'll wait snd see.

[p fandango]

hmm hate to say this, but if you were getting fuel cut before then the RIP kit might make it worse because it should spool quicker & slightly higher

what boost you running & assume your using a standard ecu & a mbc?

[cherry1809]

Nope. HLM304 and Blitz SBC. Exhaust is really black, So runnimg rich as hell.
Oh, And 1.2 bar.

[bigrotch]

Hlm takes out the fuel or puts it alot higher I've boosted up to 21/22psi and and never hit fuel cut in 304hlm the standad Ecu fuel cut Is a constant 15psi as pf said rip kit u will hit it alot quicker

[cherry1809]

Not fuel cut, Just seems like it. It's fine before and after about 3500k. It never did it when the ecu was first put on, It's just started. Making me think there is, Or was a vac leak somewhere.

The problem could be with the boost limits.

If it is happening at a certain rev range then it might be that you are exceeding the boost limit for that rpm. The ecu would normally back off the boost after detecting boost over a set limit using the BCS, but because you ahve an external unit controlling the boost then the ecu goes to the next stage which is the cut.

A remap will either completely remove the boost limit (not good really) or just increase it. The limits can be increased at different RPMs so for example between 0 and 2000rpm the limit might be 8psi, and then 2000-300rpm say 10psi then after that say 15psi.

What boost levels are you running below 3500rpm?

thats what i thought, but he's already got a HLM304

[Dangerous Dave]

Yeah but the HLM304 might have boost limits at lower rpm. The best thing to do is ask Hamish what the boost limits are below 3000rpm on the 304 map (thats if that kind of information will be shared, as usually it is a closely guarded secret)

If he's hitting 15psi at 3000rpm and the ecu limit is 12psi then the ecu will do its best to stop the boost (as it is programmed to do that)

[cherry1809]

I only hit 1.2 bar at the lower end (About 3k) Above 3.5k I only get about a bar. Or did. Still haven't tried it since changing this lot yet.

[Jamest5r]

How harsh is the boost cut? is it's like it's just missing a bit and not pulling smoothly or just all gone if you get what i mean

LOL, thats 17.5psi at 3000rpm. I'm not sure what the maximum boost a HLM304 map reaches (at any RPM) but I'd say that that amount of boost at that level would be above the HLM304 limit

[nottsgreent5]

i made a preasure tester for the turbo i had a massive leek on the o ring on the base of the vac tree at the time it was very rich 15mpg and boost was very eratic

Right, I'm a bit more sober this morning. Lol.
Whenever the boost starts to creep in is when it hits the maximum I've set the Blitz at. I'm not a 100% where that is as I never use full throttle from below 3k anyway. I was just assuming thats where it starts to get full boost. It happens at the same point in 4th and 5th but not the lower gears. Just stops until I back off the throttle, Take it past 3.5k then I can wot again.

[cherry1809]

Oh, And just to throw another spanner in the works. It does it on low boost too.
I've yet to check the lambda sensor too, And is there usually any issue with the fpr?
Haven't had any fault light come up as of yet.

[T4Rick]

I thought the boost limit was 13psi lol before any thing would cut in.Think im at about 9psi

[cherry1809]

Boost limits low on a standard ecu. I'm not running a standard ecu.

[T4Rick]

Would you happen to know what the boost limit is on the std ecu

[cherry1809]

Think someone said about 15psi, So you should be able to run 1 bar boost.
