If theyre happy right now, then Id hate to see them unhappy

rkostolni

I am not happy at this point, but I still have hope that Scott will work out these issues. I think this could really be a great product that I would really like to keep. This is the first batch, think about how f'd up Mazda's first batch of Rx8's were.

epitrochoid

a shot in the dark, but can we use the greddy dongle on the PCM still to fool it??

rkostolni

I thought about that, but at the least it would totally throw off the maps because the car would then be using cold enrichment.

epitrochoid

i assume the dongle goes on the water temp wire? just connect it so that the "dongeled" output only goes to the PCM not the interceptor. that wont affect the maps.

MazsportScott

Guys,
Please DO NOT connect any emanage dongles to the Interceptor-X wiring. If you notice the codes that have been popping up are because the system is too rich. There is actually nothing "wrong" other than the factory ECU is seeing the "rich" values and determining that they are to "rich" for a stock non turbo car. The factory ECU is correct, the AFR's these guys are viewing are too rich for a non-turbo car. If you run a Turbo car at 13.0-1 AFR's hard (under boost) you will at some point have an engine failure. As I stated before, the CEL will perform as Mazda intended. If we fool the factory O2 sensor then using it to monitor AFR's will no longer be accurate. Scott

epitrochoid

but would it be ok to fool it if we had an aftermarket wideband?

rkostolni

Were not using the stock widebands to monitor the AFR though. At least not at this point. Or am I mistaken and it is being used in some way?

truemagellen

so there are going to be CELs? and this is normal?

PUR NRG

I can't speak about Scott initially promising there would be no CELs, but I was getting the "system too rich (bank 1)" CEL all the time with the eManage. So in that respect it's nothing new for Greddy owners.

Scott called me twice today. After our last conversation over the weekend he thought to ask if I had installed the spark plugs I purchased from him. I hadn't, and he thinks that's the cause of my ping--the maps were developed using RX-7 plugs in mind. Where the RX-8 normally has 7s leading and 9s trailing, his plugs are all 9s. The trailing plugs use two crush washers as spacers. The leading plugs don't use the spacers.

I don't know if I'll be able to change plugs until the weekend but that's the current best guess why I was having problems.

drifter_d

uh, oh. CELs will cause me some issues when emissions testing time comes....

TORacing

a normal aftermarket wideband fooler will not work on our cars because our factory 02s are different than other widebands.

truemagellen

thank goodness I live in an emissions free state...cat deletion pipe is on my list of goodies to buy

ScudRunner

Scott told me that the CEL would flash if the factory knock sensor picks something up.

epitrochoid

that's not going to fix the CEL though. in fact you'll get a CEL without a turbo at all. (yea I know there's a fix using some sort of spacer, but I'm no so sure about its long term reliability)

i have no idea how the interceptor is specifically wired, nor the emanage that ships with the greddy kit...but I'd assume one of the dongles on the emanage harness tricks the PCM into thinking the car is always warming up, so that it can get away with richer than acceptable AFR's. my guess is it caps the water temp sensor output to just under the threshhold for being totally warm. so why can't you just feed the interceptor the true water temp signal (so that it runs the correct hot or cold map when appropriate) and send the PCM a capped signal to supress the CEL?

i'm just throwing ideas out there. of course scott knows these things better than any of us ever will, but I myself cannot live with a CEL constantly on. you'll never know when a new code has come up without constantly monitoring it with a can reader, not to mention it's ugly!

Wouldn't the turbo itself cause you problems come emmission time anyway

drifter_d

Good point. but a lit CEL would do it, turbo or not. hopefully, there's a fix to be had....

rkostolni

The turbo itself should not cause you to fail emissions except maybe in California, provided you have no CEL's. The turbo should pass a smog test as long as you have a cat. Greddy has even submitted it for CARB approval, although it will be a few years before it actually has certification.

it depends which state you're in, here in TX there is no visual, just a sniffer/CEL test

adrian-1

And the sniffer test they do an idle rev to like 2-3k rpms, so the turbo won't even spool up.
Yeah, you won't pass with a CEL.

rkostolni

Adrian, have you gone under boost yet with the Interceptor?

RXhusker

Wouldn't you just clear all your CEL's just prior to the inspection? As long as you don't go into high boost again before the inspection there won't be a CEL light.

I am out of town unfortunately til the weekend -- hopefully can install mine then.

Speedrx8er

RXhusker if you don't have time you can always ship it to me in MN and i'll install it on my car ahhahahah :D

adrian-1

Yes. No detonation at 10psi. I also got my idle AFR's up to 12.5:1 (was at 11.0). Dynotuning next week to get the most out of it (WOT AFR's in the 10's, need to lean it out a bit.)

rkostolni

Before you turned up the boost did you notice any significant power difference between the Interceptor and the Emanage?
