M20 throttle response

[E30godz]

Does anyone else with an M20 notice a shitty throttle response from idle? there is a very noticeable delay in when i stab the gas and the revs hop at low RPM's...in my car at least!

[bwanac]

Yes, but I have an eta. It seems to be that way in most cars though!

[Rob]

have you checked the slack in the throttle cable? there should be adjustment on the throttle body, try tightening that up, might help a bit

[bwanac]

I did that w whle ago , it did not chagne the ohms in the pdeal.! Damn physics!

I suck at typing. Damn power hour! :D

[randomtask37]

i know exactally what your talking about. but once it gets above 3k its got great responce.

[bwanac]

Yeah, same in my car. Of course aboe 3k I nonly got about 1k to go till redline!

Anyone got a spare m50/s50 lying around?

ok good, i was hoping i didnt have a huge vacuum leak somwhere...i wonder if a lightwheel flywheel would eliminate a lot of that...and maybe a not so damn restrictive exhaust

even our 1992 4.0 manual Cherokee has better response off the low end...maybe a MAF would help

[SlammedE30]

It's the AFM that causes such shitty throttle response. A MAF would greatly improve it.

If I go WOT from zero, my car will take a second to reach 1k rpms and then take off. I assume we have the same problem. Time for a MAF then :P

Its one of the "gifts" of the AFM, my s14 does it as well. I want a MAF for this reason alone.

I have the same problem, probably worst than you, the damm AFM is the problem I think, it's a bit difficult to tune.

I wonder if the flywheel will elimante this too...but someone told me not get a light Flywheel when you have a turbo, don't remember the problem.

Can't wait to put my MAF and tune it with the SMT6 , hope with this will elimanate this problem

Also, I found from what I tested, the Euros M20 has more Throttle response than US bimmers, with the same M20, why? probably and from what I know is for the higher CR, I'm not so sure if the Euro has higher CR but I'm pretty sure is the main fact.

[Rob]

the euros cars dont have cats either, might have an effect on response.


btw- diego your problem is that turbo haha

[TCD]

Hmm, all my AFM equipped cars have great throttle response. Don't blame the AFM. You likely have some other deficiency. It's amazing how better a car with 150-200k runs when you actually replace some of the wear items in the ignition and fuel systems.

bad bad ROb...niether are the problems..

I tell you this cuz...I have that problem before putting the turbo,( I bought the car with that crappy response already) so no lag or kind of...

Second, CAT or No CAT doesn't affect any shitt in that, why? CUz I took off the CAT when I bought the car...I have free flow exahust(Nod amm regulations here, I love this) and didn't notice almos any gain, niether in the Throttle response... ;)
