I don't run X chip so I can't say a thing...looks odd though that it would spike like that.

With my M-box this shows me why I don't want APR v3.3. ABT looks smooth & X has da powa! - shaneS4 2003-03-26 14:52:17 (1391 views)

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 (1699 views)

Yes, but it's still the best software on the market ;) - Argeiphontes 2003-03-26 18:32:54 (1179 views)

You would have to quantify that statement. - Milpitas2.7T 2003-03-26 19:40:19 (1131 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 (1325 views)

Actually no, here;'s why.. - Milpitas2.7T 2003-03-26 19:37:42 (1335 views)

Not true...MTM has sent engineers here. - RichP 2003-03-27 06:30:58 (1078 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 (795 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 (1043 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 (4043 views)

P.S. Confirms that short shifting is the way to go. - PhoenixS4 2003-03-26 13:51:14 (783 views)

Not if the final output torque with tranny gearing is still higher. (Which it probably is.) - BryanGT 2003-03-26 16:57:31 (621 views)

It matters where in the rev range you make that torque. HP = (torque x RPM)/5252. - 2k2S4 2003-03-26 13:51:07 (634 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 (755 views)

Many Thanks. Great Work. I Love my X Chip!!!!!!! - S4SPEED-VA 2003-03-26 13:11:32 (987 views)

do they still have the data - can they plot APR vs MTM - that looks interesting - Mark P 2003-03-26 13:01:06 (741 views)

I can ask Todd, or Todd can you do it and post it here ? - xccess 2003-03-26 13:02:56 (679 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 (569 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 (828 views)

Yes, v3.3.. - LightWeight 2003-03-26 12:48:42 (647 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 (721 views)

Not really comparable, it depends on too many factors, the dyno itself being one of them. - 2k2S4 2003-03-26 12:46:03 (520 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 (625 views)

Manifold pressure Vs. RPM, and the dyno's wideband O2 vs. RPM... - BryanGT 2003-03-26 12:47:22 (875 views)

003 (airflow and timing) for sure, maybe 115 (boost), 002 (air and fuel) - DarinS4Turbo 2003-03-26 12:46:43 (672 views)

I assume we can do all three block at the same time right ? - xccess 2003-03-26 12:51:48 (550 views)

Like Bryan said wideband is best, then just do 115 (manifold pressure) and 003 (timing/air) - DarinS4Turbo 2003-03-26 13:17:25 (562 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 (613 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 (550 views)

How's this for a thought: - 2k2S4 2003-03-26 12:01:40 (1050 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 (626 views)

Agreed... - Milpitas2.7T 2003-03-26 12:42:50 (692 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 (577 views)

yes 1.2+ bar at that rpm is within spec as per the compressor maps! - SlvrBulletS4 2003-03-26 12:06:28 (683 views)

Ok, well in my humble opinion the X-chip is still unrefined... - s4IRIsH 2003-03-26 12:18:59 (642 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 (711 views)

Was this APR's 93 octane program or the 91 running on 93? - used2bmcouper-nowa6r 2003-03-26 11:13:21 (866 views)

93 Octane V3.3 - The Reaper 2003-03-26 21:29:28 (641 views)

It looks more like the 85 octane program based on the timing. - DarinS4Turbo 2003-03-26 11:17:51 (719 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 (728 views)

Yea so my APR chip is a big freaking POS....lots of torque though - used2bmcouper-nowa6r 2003-03-26 11:26:55 (1291 views)
