Unfortunately that is a misrepresentation to get you to spend big bucks, it's AMS not ABT software - Milpitas2.7T 2003-03-26 15:18:52 (1684 views)

Yes, but it's still the best software on the market ;) - Argeiphontes 2003-03-26 18:32:54 (1170 views)

You would have to quantify that statement. - Milpitas2.7T 2003-03-26 19:40:19 (1122 views)

Tory, that's not really fair. I'm not disagreeing with you, but by that logic, MTM isn't MTM - 2k2S4 2003-03-26 16:44:48 (1311 views)

Actually no, here;'s why.. - Milpitas2.7T 2003-03-26 19:37:42 (1326 views)

Jo Hoppen is nothing more than an MTM distributor... - NonBenz OZ SL GB 2003-03-26 19:40:26 (1268 views)

Not true...MTM has sent engineers here. - RichP 2003-03-27 06:30:58 (1071 views)

True, but that still doesn't change the fact that Hoppen is an MTM reseller. - NonBenz OZ SL GB 2003-03-27 06:58:42 (790 views)

right, like I said below, Strat sold MTM, which was the same MTM chip that anyone had... - Mark P 2003-03-27 09:28:52 (1070 views)

How can ABT make less torque, but 30 HP more at 500 rpm less than APR? Confusing. - PhoenixS4 2003-03-26 13:44:23 (1035 views)

APR's tuning on the M-box is either tuned very conservative or they have something wrong with the - The R 2003-03-26 17:05:01 (4019 views)

P.S. Confirms that short shifting is the way to go. - PhoenixS4 2003-03-26 13:51:14 (778 views)

Not if the final output torque with tranny gearing is still higher. (Which it probably is.) - BryanGT 2003-03-26 16:57:31 (612 views)

It matters where in the rev range you make that torque. HP = (torque x RPM)/5252. - 2k2S4 2003-03-26 13:51:07 (626 views)

Well the peak torque was at the same rpm, but I guess the APR tq curve falls off faster. - PhoenixS4 2003-03-26 13:53:12 (747 views)

Many Thanks. Great Work. I Love my X Chip!!!!!!! - S4SPEED-VA 2003-03-26 13:11:32 (977 views)

do they still have the data - can they plot APR vs MTM - that looks interesting - Mark P 2003-03-26 13:01:06 (733 views)

I can ask Todd, or Todd can you do it and post it here ? - xccess 2003-03-26 13:02:56 (671 views)

Results look very similar to our dyno tests. - tuan@grdperformance.com 2003-03-26 12:54:34 (843 views)

Thanks for doing this, now compare to mine that i did sometime ago - Milpitas2.7T 2003-03-26 12:49:59 (865 views)

So the dyno proves our tests were right.. APR mbox is slow :/ - LightWeight 2003-03-26 12:48:10 (907 views)

It's AARP, and I don't see how that's going to do you any good unless you like eating dinner at 4:30 - 2k2S4 2003-03-26 12:57:13 (566 views)

APR v3.3? I've seen a 2000 A-box v3.3 dyno 23hp/27lb-ft more than a 2001.5 M-box v3.2 - Third ROC 2003-03-26 12:40:30 (817 views)

Yes, v3.3.. - LightWeight 2003-03-26 12:48:42 (640 views)

That same 2000 APR A-box was 8hp less but 2 lb-ft more than a 2001.5 M-box GIAC X chip. - Third ROC 2003-03-26 12:46:31 (713 views)

Not really comparable, it depends on too many factors, the dyno itself being one of them. - 2k2S4 2003-03-26 12:46:03 (515 views)

The cars I'm talking about were on the same dyno. The v3.2 runs were from several 2001+ cars. - Third ROC 2003-03-26 12:48:51 (616 views)

Looks like ABT and MTM have their shit together. Where are the MAP and A/F graphs? - BryanGT 2003-03-26 12:25:55 (806 views)

what block on VAG 002 ? - xccess 2003-03-26 12:36:45 (580 views)

no but it is possible if the request is make.. - xccess 2003-03-26 12:40:25 (639 views)

Manifold pressure Vs. RPM, and the dyno's wideband O2 vs. RPM... - BryanGT 2003-03-26 12:47:22 (862 views)

003 (airflow and timing) for sure, maybe 115 (boost), 002 (air and fuel) - DarinS4Turbo 2003-03-26 12:46:43 (665 views)

I assume we can do all three block at the same time right ? - xccess 2003-03-26 12:51:48 (542 views)

Like Bryan said wideband is best, then just do 115 (manifold pressure) and 003 (timing/air) - DarinS4Turbo 2003-03-26 13:17:25 (553 views)

Yes, but you'll only get 1 sample per second that way. Do them seperately for a better sample rate. - 2k2S4 2003-03-26 12:55:29 (605 views)

Air fuel is more accurate when read externally (Wideband); you should be able to read 2 blocks... - BryanGT 2003-03-26 12:55:17 (546 views)

How's this for a thought: - 2k2S4 2003-03-26 12:01:40 (1042 views)

lol poor MTM....the beer bitch. - SlowestS4Here 2003-03-26 12:27:40 (912 views)

And what about this dyno from AWE WebSite ??? 389 lbs-ft torque - Chuck-S4 2003-03-26 11:51:55 (1125 views)

different cars different run, can not be compare.. just like when I go to different dyno system - xccess 2003-03-26 12:49:21 (654 views)

Chuck definitely not comparable - Prodigy 2003-03-26 11:58:56 (643 views)

No, those are wheel numbers on that dyno. That's what an X will dyno on the dyno I've been on. - The R 2003-03-26 12:12:17 (679 views)

I'm talking about the 389 number he brought up - Prodigy 2003-03-26 12:13:52 (557 views)

Oh ok, gotcha. My bad...I'm in a hurry so I'm not paying attention. :-p - The R 2003-03-26 12:18:46 (537 views)

Many factors I know ; but I did buy my chip based on that dyno sheet. - Chuck-S4 2003-03-26 12:00:43 (585 views)

it could , but I highly dout it since ABT was a first chip that ran - xccess 2003-03-26 11:40:40 (770 views)

Great work! That X -chip dyno is NOT smooth. Confirms what I felt when testing it. - Argeiphontes 2003-03-26 11:35:31 (983 views)

For all that say the X is unrefined or overkill. Go buy an A4 give me the booooost! - BLK01S4 2003-07-02 09:08:44 (618 views)

Nice work. X chip has a serious a torque peak. - Symbiotic 2003-03-26 11:28:01 (836 views)

Has anyone elaborated on whats producing the spike ? - Prodigy 2003-03-26 11:33:44 (678 views)

It is pretty aggressive. However I was only seeing 15-17 PSI - Symbiotic 2003-03-26 11:49:17 (717 views)

Theres a name for people who only care about peak power. Starts with "Dyno", ends with "Queen". :-P - BryanGT 2003-03-26 13:22:58 (636 views)

I'm not talking about the "spike in power", but the large 1.5 bar boost spikes... - s4IRIsH 2003-03-26 12:02:12 (798 views)

XR = 1.5+bar and is unrefined. But vers.8 X is very smooth, controlled, and refined IMO. - DarinS4Turbo 2003-03-26 12:33:39 (624 views)

Agreed... - Milpitas2.7T 2003-03-26 12:42:50 (685 views)

I'm guessing every one of those chips boosts above 1.2 bar. 1.3 peaks seem to be par for the course. - 2k2S4 2003-03-26 12:09:54 (574 views)

yes 1.2+ bar at that rpm is within spec as per the compressor maps! - SlvrBulletS4 2003-03-26 12:06:28 (681 views)

Ok, well in my humble opinion the X-chip is still unrefined... - s4IRIsH 2003-03-26 12:18:59 (639 views)

Cut the X some slack man ;-). Also the fact the X runs a little richer is a plus. - Symbiotic 2003-03-26 12:43:06 (707 views)

Hmmm, that would have been fun... - s4IRIsH 2003-03-26 12:49:13 (623 views)

Was this APR's 93 octane program or the 91 running on 93? - used2bmcouper-nowa6r 2003-03-26 11:13:21 (857 views)

93 Octane V3.3 - The Reaper 2003-03-26 21:29:28 (633 views)

It looks more like the 85 octane program based on the timing. - DarinS4Turbo 2003-03-26 11:17:51 (708 views)

APR actually seems to have better low end hp & torque than Abt. Just loses it above 4k RPMs - Mark P 2003-03-26 11:52:56 (718 views)

Yea so my APR chip is a big freaking POS....lots of torque though - used2bmcouper-nowa6r 2003-03-26 11:26:55 (1284 views)

Once they fix the timing above 4000rpm APR will be up there with the rest. - DarinS4Turbo 2003-03-26 12:17:20 (541 views)

Nice - totally agrees with my VAG acceleration results. X > ABT > MTM > APR. By the way, - DarinS4Turbo 2003-03-26 11:07:02 (1005 views)
