Thank You Sir... I am in the Security, Audio and Fire Safety Business... so don't use my meter for these types of applications lol.. mainly I have 87 III for the true RMS on Audio Signals... of course the record feature is nice also for watching a circuit overnight or whatever... Again Thanks -...

Maybe I am missing something, thought it was a pulsed 5vdc signal? Oh yeah duh, read it under DC then hz for the frequency of the 5vdc right? I mainly want to see that at a given rpm is the frequency consistent and does it rise consistently with rpms... figured the best way to test the...

Siemens Injectors flow tested at 559cc all under 2% variance, static test, 3msec and 6msec tests... all was good. Now that I have Plenum off, will remove intake and check level of all surfaces... as #1 plug fouled out from fuel with 15 minutes of running, so a vacuum leak in that area is my...

After re-testing coil, ingnitor, ignition wires, resistor pack, resistance of injectors and on and on... I have pulled the plenum and now have pulled the injectors. I am going go do what I should have 4 months ago when they came in, get them flow tested by a fuel injection shop... One point...

Yikes, my head and block both were done to about a RA value of 12-14... like GrimJack said, should be like a mirror... As far as I am aware there is no way to have it machined right without dis-assembling it... Good Luck, for sure find a new machine shop and ask for a refund from Barney and...

If you are referring to the fact that the o-ring is simply different for domestic, why would anything else matter? They are 2-3 ohm resistance rated at 550cc. If the flow chart shows them to be accurate, what else is the difference? If IIRC correctly I looked this up and the part number is the...

Thanks Nick, yeah that makes sense. I changed back to my known good stock ignition wires, new plugs gapped to .26, I also double checked all intercooler connections, after being heated up a few times, seemed like a get get a couple of turns from each one... also create a little more restriction...

Thanks for the explanation and nope sure don't have an analyzer handy... Well since that was shunted, it was found during my tear-down, I have had a total re-build, which included new 550cc injectors, so I took out the shunt when cleaning up harness. I have double checked resistance of...

OK, so I guess the unburned mixture of gas and air are not able to be read by the O2 sensor? So do you have an idea outside of misfire or are you just saying you are not sure but don't think it is a misfire? hope my question makes sense :icon_bigg Yeah gotcha lol, I have been using to...

Hey Kenny - Nope no codes. Have double checked CPS connections and timing all good, I replaced CPS wires back about 12" to eliminate cracks etc... Yeah I have a Fluke 87 meter, what am I looking for? voltage leaks? Would be greater than 12vdc though... Was I making sense though, I know it...

So a quick update, I have added a restriction screw now to the un-metered air port in the lexus afm body, all the way in should be blocking 80% or so, reset efi, neo is completely disconnected (has to be sent back to factory for firmware anyway, so thought that was my issue). It still ran really...

Well I do have 122 miles on it so far and that is what I did in order to compensate, but I guess my concerns is that it seems to be a common theme throughout numerous threads that I have read, that it is best to lest the TCCS do its job up to 69% throttle, so that has me concerned that something...

Ok, I will pull AFM and see where how far it is in right now, I think it came off a lexus before I got it, so I assume it was where the lexus ran at stock. Yeah that was my next step, you are right it is Vf1 and E1, it ranges from 0vdc to 5dvc app, about 2.2vdc should be base-line, more it is...

NickM - Thank you for the clarification - I will double check resistance on pins of the lexus afm, i did test once before, it also does not throw a code... in reading the article from someone documenting this upgrade, I thought the sequence was, unmetered air would cause O2 sensor to say I am...

To begin with I am going to list mods so that is an understanding of how I got to where I am: 1988 5spd 7mgte Motor & tranny top to bottom complete re-build - Stock internals Greddy 2.0mm MHG ARP Head, Main & Rod Bolts Upgraded oil pump (BP'd for higher flow) Arizona Performance HF Oil...

AMEN - Whether you are buying Crap or Quality, they are all marketed on Ebay... There are several AEM Dryflow setups listed on Ebay... Summit Racing has an Ebay Store, you can find, Greddy, HKS, AEM, ARP and on and on and on listed on Ebay... You have to be a knowledgeable buyer, watch how the...

IMO - You need the head bolts, yet I am making assumptions as to what upgrades you will be doing to get to 400hp... the Main and Rods, once again imo are a good idea, perhaps not needed, but a in-expensive upgrade during a re-build. So my statement made another assumption that you did not say...

So did the test with the TPS using the CEL, yep got a code 51 with just a hair bit of throttle and went away after releasing. Reset EFI, it helped a little, but not too much, about 16.8 - 16.9... Did some 2nd - 4th gear pulls to 4k with it, felt real good, only went to 0 boost/vacuum... but I...

Yeah good point, I did not reset EFI after adjusting FP, I will do that this evening and see if that helps the idle AFR. Yeah the higher throttle stuff will come a little later, at this point I have my Neo set at 69/70 and do not plan to go past 70% or even 50% until I get passed my 5 heat...

I used a fluke 87 digital meter myself and I just set it with sounder on for continuity, so I just adjusted until the sounder went off... (you are just measuring across a N/C switch, that opens when throttle opens) although I had problems with using feeler gauge, so adjusted it my sight and once...
